Southwest Airlines Co. (NYSE: LUV) is a major U.S. airline and the world's largest low-cost carrier, headquartered in Dallas, Texas. The airline was established in 1967 by Herb Kelleher and adopted its current name (Southwest Airlines) in 1971. The airline has nearly 46,000 employees as of December 2014 and operates more than 3,800 flights per day. As of 2014, it carries the most domestic passengers of any U.S. airline. As of November 2015, Southwest Airlines has scheduled service to 97 destinations in 40 states, Puerto Rico, and abroad.

Southwest Airlines has used only Boeing 737s, except for several years in the 1970s and 1980s, when it leased some Boeing 727s from Braniff. As of August 2012, Southwest is the largest operator of the 737 worldwide with over 650 in service, each averaging six flights per day.

History

Early history

Southwest Airlines began with the March 15, 1967, incorporation of Air Southwest Co. by Rollin King and Herb Kelleher to fly within the state of Texas.

Kelleher believed that by staying within Texas, the airline could avoid federal regulation. Three airlines (Braniff, Trans-Texas and Continental Airlines) started legal action which was not resolved for three years. Air Southwest prevailed in 1970 when the Texas Supreme Court upheld Air Southwest’s right to fly within Texas. The Texas decision became final on December 7, 1970, when the U.S. Supreme Court declined to review the case, without comment.

The story of Southwest’s legal fight was turned into a children’s book, Gumwrappers and Goggles by Winifred Barnum in 1983. In the story, TJ Love, a small jet, is taken to court by two larger jets to keep him from their hangar and to stop him from flying. In court, TJ Love’s right to fly is upheld after an impassioned plea from a character referred to as "The Lawyer." While no company names are mentioned in the book, TJ Love’s colors were those of Southwest Airlines, and the two other jets are in Braniff and Continental colors. The Lawyer resembles Herb Kelleher. The book was adapted into a stage musical, Show Your Spirit, sponsored by Southwest Airlines and played only in cities served by the airline.

On March 29, 1971 Air Southwest Co. changed its name to Southwest Airlines Co. with headquarters in Dallas. Southwest began scheduled flights on June 18, 1971, Dallas to Houston (initially IAH) and Dallas to San Antonio with three 737-200s. The OAG for 15 October 1972 shows 61 flights a week each way between Dallas and Houston Hobby, 23 each way between Dallas and San Antonio and 16 each way between San Antonio and Houston; no flights were scheduled on Saturdays.

Southwest Airlines founder Herb Kelleher studied California-based Pacific Southwest Airlines and used many of PSA’s ideas to form the corporate culture at Southwest. Early flights used the same "Long Legs And Short Nights" theme for stewardesses on board typical Southwest Airlines flights. A committee including the same person who had selected hostesses for Hugh Hefner's Playboy jet selected the first flight attendants, females described as long-legged dancers, majorettes and cheerleaders with "unique personalities." Southwest Airlines and Herb Kelleher dressed them in hot pants and go-go boots.

The New York Times wrote in 1971 that Southwest Airlines President Lamar Muse, "says frankly—and repeatedly—that Southwest Airlines has been developed from its inception around the ideas that have proven to be successful for Pacific Southwest Airlines." "We don't mind being copycats of an operation like that," referring to a visit he and other Southwest executives made to PSA as they assembled their operating plans. PSA welcomed them and even sold them flight and operations training. Muse later wrote that creating the operations manuals for his upstart airline was "primarily a cut and paste procedure" and it is said that "Southwest Airlines copied PSA so completely that you could almost call it a photocopy."

The rest of 1971 and 1972 saw operating losses. One of the four 737s was sold to Frontier Airlines and the proceeds used for payroll and other expenses. Southwest continued a schedule based on four aircraft but using only three, so the "ten minute turn" was born and was the standard ground time for many years.

Wright Amendment

The Wright Amendment of 1979 is a federal law that governs traffic at Dallas Love Field, the pre-1974 airport in Dallas. It originally limited most nonstop flights to destinations within Texas and neighboring states. The limits began to phase out in 1997 and 2005; in 2006, the amendment was repealed, with some restrictions intact until 2014, but added a restriction on the number of gates allowed.

When airline deregulation came in 1978, Southwest began to plan interstate flights from Love Field, causing groups affiliated with Dallas/Fort Worth International Airport, including the city of Fort Worth, Texas, to push the Wright Amendment through Congress to restrict such flights. Under the amendment, Southwest and other airlines were barred from operating or even ticketing passengers on flights from Love Field to destinations beyond the states that border Texas. The Wright Amendment’s restrictions did not apply to aircraft with 56 or fewer seats; Southwest did not use the 56 seat loophole. Southwest's first schedule out of Texas was Hobby to New Orleans about February 1979.

In 1997 Southwest’s efforts paid off with the Shelby Amendment, which added Alabama, Mississippi and Kansas to the allowed destinations. Southwest began nonstop service between Dallas Love Field and Birmingham, Alabama.

Network expansion

Southwest just flew to Dallas Love Field (DAL), Houston (IAH, then HOU) and San Antonio (SAT) until 1975 when it added Harlingen. In 1979 Southwest flew to eleven Texas cities and added its first route out of the state, Houston-New Orleans, around the end of the year. In 1980 Southwest expanded north to Tulsa and Oklahoma City and west to Albuquerque; in 1982, north to Kansas City and west to Phoenix, Las Vegas and California.

Flights to Denver started in 1983 (and ended in 1986), to Little Rock 1984, to St Louis and Chicago Midway in 1985, to Nashville in 1986 and to Detroit Metro and Birmingham in 1987. Eastward expansion resumed in 1992 with Cleveland and Columbus, then Baltimore in 1993. The Pacific Northwest started in 1994 after the Morris Air takeover; Tampa and Fort Lauderdale started in January 1996. East to Providence in 1997, Manchester in 1998, and Islip and Raleigh-Durham in 1999.

Southwest's only route within California was San Francisco-San Diego until the airline started flying in Oakland in 1989; in the next few years its capacity on the West Coast ballooned.

1980s–2000s

Southwest hired its first black pilot, Louis Freeman, in 1980. In 1992, he was named the first black chief pilot of any major U.S. airline.

In 1981, Southwest was successfully sued for its then-existing policy of hiring only female flight attendants and ticket agents.

Southwest's Houston Pilot Base opened on June 1, 1984. Houston was its first crew base outside Dallas.

On November 30, 1984, Southwest took delivery of their first Boeing 737–300. Southwest was the launch customer and as of May 2012 is the largest operator of the aircraft type. The first 737-300 was dubbed "Kitty Hawk."

Southwest paid US$60.5 million in stock and cash for Muse Air when Muse was on the verge of collapse in 1985. After completing the acquisition, Southwest renamed MuseAir TranStar Airlines. TranStar became a wholly owned subsidiary of Southwest and operated as an independent airline. Unwilling to compete in a fare war against Frank Lorenzo's Texas Air, Southwest eventually sold TranStar's assets to Lorenzo in August 1987.

Southwest moved into their current headquarters in 1990. Previously, the airline was headquartered in the 1820 Regal Row building in Dallas, by Love Field. At that time the headquarters had 256,000 square feet (23,800 m²) of space and approximately 650 employees. The current headquarters facility was built at a cost of $15 million in 1990 dollars. In early 1995 the building received an additional 60,000 square feet (5,600 m²) of space. As of 2006 about 1,400 employees worked in the three story building.

In 1990, the airline registered their aircraft in Houston so they could pay aircraft taxes in Houston, even though the actual corporate headquarters were in Dallas. Southwest was not physically relocating any assets, but Texas state law allowed the airline to choose either Dallas or Houston as the city of registry of their aircraft.

Southwest acquired Morris Air, a competing airline based in Salt Lake City, Utah, in 1992, paying US$134 million in stock. After completing the purchase, Southwest absorbed the capital and routes of Morris Air into Southwest's inventory and service, including Morris' Pacific Northwest destinations not previously served by Southwest. One founder of Morris Air, David Neeleman, worked with Southwest for a short period before leaving to found WestJet and then JetBlue Airways, a competing airline.

On March 16, 1995, Southwest became one of the first airlines to have a website. Originally called the "Southwest Airlines Home Gate," passengers could view schedules, a route map and company information at Iflyswa.com. Southwest.com is the number one airline website for online revenue, according to PhoCusWright. Nielsen/Netratings also reports that Southwest.com is the largest airline site in terms of unique visitors. In 2006, 70 percent of flight bookings and 73 percent of revenue was generated from bookings on southwest.com. As of June 2007, 69 percent of Southwest passengers checked in for their flights online or at a kiosk.

Southwest Airlines gained a reputation for "outside the box thinking" and proactive risk management, including the use of fuel hedging to insulate against fuel price fluctuation. Some analysts have argued against the style of profit-motivated energy trading Southwest did between 1999 and the early 2000s. They suggested that rather than hedging business risk (such as a hedge on weather to a farmer), Southwest was simply speculating on energy prices, without a formal rationale for doing so.

At present, Southwest has enjoyed much positive press (and a strong financial boost) from their energy trading skills. However, while most analysts agree that volatility hedges can be beneficial, speculative hedges are not widely supported as a continuing strategy for profits.

In March 1996, after the Dallas City Council unanimously voted to allow for construction, the airline began to build a 300,000 square feet (28,000 m²) addition to the existing corporate headquarters at a cost of $30 million in 1996 dollars. This occurred after, on Wednesday March 13, 1996, . The airline leased two additional tracts of land, a total of 10 acres (4.0 ha) of space, from the City of Dallas to build a new pilot training facility, a headquarters expansion, and additional parking spaces. A $9.8 million new pilot training facility was built on a 5 acres (2.0 ha) plot of land owned by the city of Dallas; it was scheduled to be completed Spring 1997. With the new pilot training facility built, the old one would be removed and the company would expand its headquarters building on the former training facility site. 120,000 square feet (11,000 m²) of building space, which had a price of $16 million including fixtures, was built, making the headquarters have a total of 436,000 square feet (40,500 m²). The airline also leased 4.8 acres (1.9 ha) from the city of Dallas to build additional parking; 700 spaces were added to the existing 1,200. After the expansion, Southwest had a total leasehold of about 24 acres (9.7 ha) of land, including its headquarters, training facilities and parking. By the end of 1997, the expansion of the facilities at Love Field and several terminal improvements were expected to cost Southwest $47 million.

2000s

Repealing the Wright Amendment

In late 2004, Southwest began actively seeking the full repeal of the Wright Amendment restrictions. In late 2005, Missouri was added to the list of permissible destination states via a transportation appropriations bill. New service from Love Field to Saint Louis, Missouri and Kansas City, Missouri quickly started in December 2005.

At a June 15, 2006, joint press conference held by the city of Dallas, the city of Ft. Worth, Dallas-Ft. Worth Airport, American Airlines and Southwest Airlines, the said parties announced a tentative agreement on how the Wright Amendment was to be phased out. Both the U.S. Senate and House of Representatives passed Wright-related legislation on September 29, 2006, and it was signed into law by President George W. Bush on October 13, 2006. The new law became effective on October 16, 2006, when the FAA Administrator notified Congress that any new aviation operations occurring as a result of the new law could be accommodated without adverse effect to the airspace.

Southwest started selling tickets under the new law on October 19, 2006. Highlights of the agreement are the immediate elimination of through-ticketing prohibitions and unrestricted flights to domestic destinations eight years after the legislation takes effect. Because of the agreement, nationwide service became possible for Southwest; the law also defined the maximum number of gates at Love Field. Southwest controls all but four of the Love Field gates. United Airlines controls two and American Airlines was initially supposed to operate from the other two, however, because of their merger with US Airways, they had to give up the two gates at DAL. Virgin America began leasing the two gates from American on October 13, 2014.

Southwest remains the dominant passenger airline at Love Field, maintains its headquarters, hangars, training centers and flight simulators adjacent thereto and reflects its ties to Love Field in its winged heart livery and its stock exchange ticker symbol (LUV).

2008–2009

In 2008, Southwest contracted with Pratt and Whitney to supply the proprietary Ecopower water pressure-washing system, which allows Southwest to clean grime and contaminants off engine turbine blades while the aircraft is parked at the gate. Frequent use of the Ecopower system is estimated to improve fuel efficiency by about 1.9%.

On March 6, 2008, Federal Aviation Administration (FAA) inspectors submitted documents to the United States Congress, alleging that Southwest allowed 117 of its aircraft to fly carrying passengers despite the fact that the planes were "not airworthy" according to air safety investigators. In some cases the planes were allowed to fly for up to 30 months after the inspection deadlines had passed, rendering them unfit to fly. Records indicate that thousands of passengers were flown on aircraft deemed unsafe by federal standards. Southwest declined comment at the time and US Representative James Oberstar advised a hearing would be held.

Southwest paid US$7.5 million to acquire certain assets from bankrupt ATA Airlines in 2008. Southwest's primary reason for making the purchase was to acquire the operating certificate and landing slots at New York's LaGuardia Airport formerly controlled by ATA. While some preferential hiring was indicated at the time of the purchase, the transaction ultimately did not include the purchase of any aircraft, facilities or transfers of employees directly from ATA.

On March 12, 2008, Southwest Airlines voluntarily grounded 44 planes to check if they needed further inspection. The FAA claimed that Southwest Airlines flew almost 60,000 flights without fuselage inspection. Southwest Airlines faced a $10.2 million fine if they violated FAA regulations. There have also been rumors that the FAA knew about Southwest Airlines violations but decided not to fine the airline because it would disrupt their services.

On March 2, 2009, Southwest settled these claims, agreeing to pay the FAA fines of $7.5 million for these safety and maintenance issues. The original fine of $30.2 million – a sum which would have been the largest fine in the agency’s history – was lowered after a year of negotiations. The FAA gave Southwest two years in which to pay the fine.

On July 30, 2009, Southwest Airlines made a $113.6 million bid for bankrupt Frontier Airlines Holdings, the parent company of Frontier Airlines. Southwest planned to initially operate Frontier as a stand-alone carrier, eventually absorbing the airline and replacing Frontier's aircraft with Boeing 737s. Less than one month after submitting its bid, Southwest learned on August 14 that it had lost the initial bidding to Republic Airways Holdings and elected not to counter or pursue the deal further. Southwest stated that its requirement for pilots' unions at both companies to reach a negotiated (not arbitrated) agreement as a condition of acquisition was a key factor in its abandonment of its bid.

On August 26, 2009 the FAA investigated Southwest for installing improper parts on about 10% of its jets. The work was performed by an outside maintenance company. The FAA stated that the parts do not present a safety danger, but the airline was given until December 24, 2009 to replace the parts with those approved by the FAA.

2010s

AirTran Airways acquisition

Southwest Airlines first announced the acquisition on September 27, 2010 and received final approval from the United States Department of Justice on April 27, 2011. On May 2, 2011, Southwest Airlines completed the acquisition of AirTran Airways by purchasing all of the outstanding common stock, corporate identity and operating assets of AirTran Holdings, Inc., the former parent company of AirTran Airways. Southwest Airlines estimates the transaction's value at $3.2 billion and expects onetime costs to integrate the two airlines of $500 million, with cost synergies of approximately $400 million annually. The greatest impact on Southwest was the elimination of a direct low-cost competitor, access to Atlanta, international service and the addition of landing slots at New York-LaGuardia Airport and Washington-Reagan Airport. Southwest obtained a single operating certificate (SOC) from the United States Federal Aviation Administration on March 1, 2012, but the airline was not fully integrated until AirTran had its last flight on December 28, 2014.

An entity called Guadeloupe Holdings was formed by Southwest and currently acts as a wholly owned subsidiary of Southwest Airlines and holding company for AirTran's current operations and assets. Southwest's organized labor groups have ceded contractual "scope" provisions pending acceptable negotiated seniority integration agreements. Southwest is transition aircraft, routes and employees from AirTran to Southwest on a one-by-one basis until all parts of AirTran have transitioned to Southwest.

The purchase adds 25 additional destinations previously not served by Southwest including cities in Mexico, the Caribbean and Atlanta, Georgia, an AirTran hub and at the time, the largest U.S. city not served by Southwest. On October 10, 2011, USA Today reported that Southwest will work to no longer bank flights in Atlanta as AirTran did. AirTran 737 aircraft are in the process of being converted to Southwest's livery and evolve interior.

On February 14, 2013, Southwest began codesharing with AirTran. It took the first step on January 26, 2013 by launching shared itineraries in five markets. Southwest continued to launch shared itineraries with 39 more markets beginning February 25, 2013. In April 2013, shared itineraries were expanded to all Southwest and AirTran cities (domestic and international). The airlines were fully integrated on December 29, 2014.

2011–present

Southwest 737-700 on final at LAX

For the tenth year in a row, Fortune magazine recognized Southwest Airlines in its annual survey of corporate reputations. Among all industries in 2004, Fortune has listed Southwest Airlines as number three among America’s Top Ten most admired corporations.

On December 13, 2011, Southwest placed a firm order for 150 Boeing 737 MAX aircraft, becoming the launch customer for the type. First delivery is expected in 2017.

In January 2012, Southwest Airlines expressed interest in serving Mexican and South American destinations out of Hobby. On May 30, 2012 Houston's city council approved Southwest's request for international flights from Hobby. Southwest agreed to invest at least $100 million to cover all costs tied to the Hobby upgrade, which includes designing and building five new gates and a customs facility. Construction at Hobby took two years, with international flights beginning in October 2015.

On April 11, 2012, Southwest introduced the 737–800 to the fleet. It seats 175 passengers as compared to the regular 143-seater 737-700. The first 737–800 was called "Warrior One" in salute of the Southwest Employees’ Warrior Spirit.

On May 5, 2014, Southwest announced that it has chosen Amadeus IT Group to replace its current domestic reservation system. Southwest already operates its international reservation system with Amadeus. The new domestic reservation system is expected to take a few years before it is implemented. When completed, Southwest will operate one reservation system by Amadeus.

In September 2014, Southwest introduced new branding, including a new livery and logo.

On October 13, 2014, the Wright Amendment restrictions at Dallas Love Field were repealed and Southwest expanded service at Love Field to include cities outside the previous location restrictions.

Throughout 2014, Southwest expanded service at Reagan-National in Washington D.C. and LaGuardia Airport in New York City through slot acquisitions from the American Airlines/US Airways merger.

Corporate identity

Advertising

The company has employed humor in its advertising. Slogans include "Love Is Still Our Field," "Just Plane Smart," "The Somebody Else Up There Who Loves You," "You're Now Free To Move About The Country," "THE Low Fare Airline," "Grab your bag, It's On!" and "Welcome Aboard." The airline's current slogan is "If It Matters To You, It Matters To Us."

A Southwest Airlines Boeing 737–700 with blended winglets (N741SA) pictured on the tarmac at Chicago Midway International Airport wearing the airline's original desert gold livery.

In March 1992, shortly after Southwest started using the "Just Plane Smart" motto, Stevens Aviation, which had been using "Plane Smart" for its motto, advised Southwest that it was infringing on its trademark.

Instead of a lawsuit, the CEOs for both companies staged an arm wrestling match. Held at the now-demolished Dallas Sportatorium (the famed wrestling facility) and set for two out of three rounds, the loser of each round was to pay $5,000 to the charity of his choice, with the winner gaining the use of the trademarked phrase. A promotional video was created showing the CEOs "training" for the bout (with CEO Herb Kelleher being helped up during a sit up where a cigarette and glass of whiskey (Wild Turkey 101) was waiting) and distributed among the employees and as a video press release along with the video of the match itself. Herb Kelleher lost the match for Southwest, with Stevens Aviation winning the rights to the phrase. Kurt Herwald, CEO of Stevens Aviation, immediately granted the use of "Just Plane Smart" to Southwest Airlines. The net result was both companies having use of the trademark, $15,000 going to charity and good publicity for both companies.

Honor Flight Network

Southwest Airlines is the official commercial airline of the Honor Flight Network. Honor Flights are dedicated to bringing aging and ailing veterans to visit the national monuments in Washington, D.C., devoted to the wars in which they served.

Corporate affairs

Headquarters

Southwest Airlines headquarters in Dallas

The Southwest Airlines headquarters is located on the grounds of Dallas Love Field in the Love Field neighborhood of Dallas, Texas.

On September 17, 2012, Southwest broke ground on a new Training and Operational Support (TOPS) building. The TOPS Building is across the street from its current headquarters building. The property includes a two-story, 100,000-square-foot operations building that could withstand an F3 tornado. It also includes a four-story, 392,000-square-foot office and training facility with two levels devoted to each function. The new facilities will house 24-hour coordination and maintenance operations, customer support and services, and training. BOKA Powell was the project architect. Manhattan Construction is the general contractor. The project is scheduled for completion in late 2013, with occupancy beginning in 2014.

Employment

As of December 2014, Southwest Airlines has nearly 46,000 employees.

Gary C. Kelly is Chairman, President and CEO of Southwest Airlines. Kelly replaced former CEO Jim Parker on July 15, 2004 and assumed the title of "President" on July 15, 2008, replacing former President Colleen Barrett. In July 2007, Herb Kelleher resigned his position as Chairman. Colleen Barrett left her post on the Board of Directors and as Corporate Secretary in May 2008 and as President in July 2008. Both are still active employees of Southwest Airlines. Kelleher was President and CEO of Southwest from September 1981-June 2001.

Labor relations

In contrast to low-cost competitor JetBlue Airways, where most employees are non-union, Southwest employees are generally members of a union. The Southwest Airline Pilots' Association, a union not affiliated with the Air Line Pilots Association, represents the airline's pilots. The Aircraft Maintenance Technicians are represented by the Aircraft Mechanics Fraternal Association (AMFA). Customer Service Agents and Reservation Agents are represented by the International Association of Machinists and Aerospace Workers Union (IAM). Flight Dispatchers, Flight Attendants, Ramp agents and Operations agents are represented by the Transport Workers Union (TWU).

Impact on carriers

Southwest has been a major inspiration to other low-cost carriers, and its business model has been repeated many times around the world. The competitive strategy combines high level of employee and aircraft productivity with low unit costs by reducing aircraft turn around time particularly at the gate. Europe's EasyJet and Ryanair are two of the best known airlines to follow Southwest's business strategy in that continent. Other airlines with a business model based on Southwest's system include Canada's WestJet, Malaysia's AirAsia (the first and biggest LCC in Asia), India's IndiGo, Qantas's Jetstar (although Jetstar now operates three aircraft types), Philippines's Cebu Pacific, Thailand's Nok Air, Mexico's Volaris and Turkey's Pegasus Airlines. Although Southwest has been a major inspiration to many other airlines, including Ryanair, AirAsia and Jetstar, the management strategies, for example, of Ryanair, AirAsia and Jetstar differ significantly from those of Southwest. All these different management strategies can be seen as means of differentiation from other competitors in order to gain competitive advantages.

Lobbying Texas rail

Southwest has fought against the development of a high-speed rail system in Texas.

In 1991, a plan was made to connect the Texas Triangle (Houston – Dallas – Fort Worth - San Antonio) with a privately financed high speed train system which would quickly take passengers from one city to the next. This was the same model Southwest Airlines used 20 years earlier to break into the Texas market where it served the same cities.

Southwest Airlines, with the help of lobbyists, created legal barriers to prohibit the consortium from moving forward and the entire project was eventually scuttled in 1994, when the State of Texas withdrew the franchise.

Destinations

Main article: Southwest Airlines destinations

As of November 2015, Southwest Airlines has scheduled flights to 97 destinations in 41 states, Puerto Rico, Mexico, Central America and the Caribbean. Southwest does not use the "hub and spoke" system of other major airlines, preferring the "point-to-point" system, combined with a "rolling hub" model in its larger cities.

Airline partnerships

Past

• Icelandair

In 1997, Southwest and Icelandair entered into interline and marketing agreements allowing for joint fares, coordinated schedules, transfer of passenger luggage between the two airlines in Baltimore and connecting passengers between several U.S. cities and several European cities. The frequent flyer programs were not included in the agreement. This arrangement lasted for several years but ended when Icelandair's service to BWI ended in January 2007.

• ATA Airlines

In a departure from its traditional "go it alone" strategy, Southwest entered into its first domestic codesharing arrangement with ATA, which enabled Southwest Airlines to serve ATA markets in Hawaii, Washington, D.C. and New York City.

At the time of ATA's demise in April 2008, the airline offered over 70 flights a week to Hawaii from Southwest's focus cities in PHX, LAS, LAX and OAK with connections available to many other cities across the United States. The ATA/Southwest codeshare was terminated when ATA filed for Chapter 11 bankruptcy on April 3, 2008. Southwest ultimately acquired the operating certificate and some of the landing rights of ATA in the ensuing proceedings.

• WestJet Airlines

On July 8, 2008, Southwest Airlines signed a codeshare agreement with WestJet of Canada, giving the two airlines the ability to sell seats on each other's flights. Originally, the partnership was to be finalized by late 2009, but had been postponed due to economic conditions.

On April 16, 2010, Southwest and WestJet airlines amicably agreed to terminate the implementation of a codeshare agreement between the two airlines.

• Volaris

Southwest signed its second international codeshare agreement on November 10, 2008, with Mexican low-cost carrier Volaris. The agreement allowed Southwest to sell tickets on Volaris flights. However, on February 22, 2013, the connecting agreement was terminated. It was said to be mutual between the airlines. Most industry experts believe that the expansion of the subsidiary of Southwest, AirTran Airways, into more Mexican markets, as a main reason for the termination of the agreement.

• AirTran Airways

After acquiring AirTran Airways in 2011, Southwest began a codeshare agreement with AirTran on February 14, 2013. The agreement ended after AirTran became fully integrated into Southwest on December 28, 2014.

Notes

• ^1 Includes orders for used 737-700s

Southwest is the world's largest operator of the Boeing 737, was the launch customer of the 737-300, -500 and -700, and will be the launch customer of the 737 Max 7 and 8.

After completing the purchase of AirTran Airways, Southwest Airlines acquired AirTran's existing fleet of 717-200 aircraft. However, Southwest elected not to integrate them into its fleet but instead sublease them to Delta Air Lines, with deliveries through the end of 2015.

Newer Boeing 737-300 variants are retrofitted with electronic flight decks and blended winglets to reduce operational costs. The retrofits make the 737-300s operationally compatible with the 737-700 and support the airline's move to embrace the Global Positioning System enabled Required Navigation Performance system.

Southwest added the Boeing 737-800 to its fleet on April 11, 2012. The aircraft has 175 seats, 38 more than the former largest plane in Southwest's fleet. All -800s include the Boeing Sky Interior, with the 8300-series -800 planes also being equipped with ETOPS equipment.

On December 13, 2011, Southwest placed a firm order for 150 Boeing 737 MAX 8 aircraft, becoming the launch customer for the type. First delivery is expected in 2017. All 737 MAX 8 aircraft will include the Boeing Sky Interior.

On May 15, 2013, Southwest became the launch customer for the Boeing 737 MAX 7 aircraft and now has 30 MAX 7 aircraft on order. The first delivery is expected in 2019.

Livery

Original desert gold livery, used until 2001

Southwest's original primary livery was desert gold, red and orange, with pinstripes of white separating each section of color. The word Southwest appeared in white on the desert gold portion of the tail. On the original three 737-200s, from June 1971, on the left side of the plane, the word Southwest was placed along the upper rear portion of the fuselage, with the word Airlines painted on the tail N21SW. On the right side, the word Southwest was on the tail, but also had the word Airlines painted on the upper rear portion of the fuselage.N20SW.

Canyon blue livery used from 2001 to 2014

Southwest introduced the canyon blue livery on January 16, 2001, the first primary livery change in Southwest's [then] 30-year history. Spirit One was the first plane painted in the canyon blue fleet color scheme. The second livery replaces the former primary color, desert gold, with canyon blue and changes the Southwest text and pinstripes to gold. The orange and red stripes continued to be used. The pinstripe along the plane was drawn in a more curved pattern instead of the straight horizontal line separating the colors in the original. For aircraft equipped with blended winglets, the blended winglets were painted to include the text Southwest.com. Southwest completed repainting its entire fleet with the new Canyon Blue livery in early 2010; however, The Colleen Barrett Classic (N714CB), The Herbert D. Kelleher One (N711HK), & The Metallic Gold One (N792SW), which are Boeing 737–700 aircraft, retain the original desert gold livery. However, these classics do not have the black paint printed on the nose of the plane and do not have the number one heart on it.

Heart livery used 2014-present

A new livery, named "Heart" and developed with firms GSD&M, Lippincott, VML, Razorfish, and Camelot Communications, was unveiled on September 8, 2014. The new livery uses a darker shade of blue. The orange stripe on the tail is changed to yellow, both the red and yellow stripes are now enlarged in reverse pattern, and the belly of the aircraft is now in blue and features a heart, which has been a symbol for Southwest during its 43-year history. Additionally, the pinstripes are changed to a silver-gray and the Southwest text, now white, has been moved to the front of the fuselage. Lettering is in a font custom designed by Monotype, Southwest Sans. The engines now feature the airline's web address, Southwest.com.

Special liveries and decals

Some Southwest aircraft feature special liveries or are named with special decals. Southwest gives these aircraft special names, usually ending in "One." All special liveries painted prior to Spirit One originally wore the standard Desert Gold, red and orange colors on the vertical stabilizer and rudder. Subsequent special liveries feature tails with the canyon blue livery. All earlier specials, with the exception of Triple Crown One, have been repainted with the Spirit livery tail. Aircraft painted in special liveries have white painted blended winglets with the exception of Warrior One which added the split scimitar winglet in May 2014. Missouri One was the first special livery to feature a modified version of the Heart tail design, with the red and yellow ribbons shrunk in order to fit the Southwest wordmark as it is unable to be used on the fuselage. Previous special livery aircraft will eventually be repainted with the new tail design, Illinois One being the first.

Notes

• ^1 The first aircraft to be painted in the "Shamu" scheme was N334SW (1988), a 737–300 and it was later followed by N507SW (Shamu II) and N501SW (Shamu III), both 737-500s. Subsequent to the retirement of Southwest's 737-200s, the 737-500s began to stay within a smaller geographic area formerly operated by the 737-200s and as such, Sea World was no longer getting the optimal national exposure from these two aircraft. Two 737–700 aircraft, N713SW and N715SW, were repainted as the new Shamu aircraft and both N501SW and N507SW were repainted in canyon blue colors. In 2013, N334SW was retired, leaving two Shamu aircraft. The artwork on the nose of each aircraft states "Shamu" plus the overhead bins on the aircraft display ads for Sea World.

Products and services

Southwest experience

Southwest operates using a unique boarding process

Southwest offers free in-flight non-alcoholic beverages and offers alcoholic beverages for sale. Southwest has complimentary peanuts or pretzels on all flights, and most flights have free Nabisco snacks. Southwest is known for colorful boarding announcements and crews that burst out in song. The singing is quite popular among passengers.

Southwest maintains excellent customer satisfaction ratings; according to the Department of Transportation Southwest ranks number one (lowest number of complaints) of all U.S. airlines for customer complaints. Southwest Airlines has consistently received the fewest ratio of complaints per passengers boarded of all major U.S. carriers that have been reporting statistics to the Department of Transportation (DOT) since September 1987, which is when the DOT began tracking Customer Satisfaction statistics and publishing its Air Travel Consumer Report.

Prior to 2007, Southwest boarded passengers by grouping the passengers into three groups, labeled A, B and C. Passengers would line up at their specified letter and board. In 2007, Southwest modified their boarding procedure by introducing a number. Each passenger receives a letter (A, B or C) and a number 1 through 60. Passengers line up in numerical order within each letter group and choose any open seat on the aircraft as part of Southwest's open seating policy.

In-flight entertainment

After completing a testing phase that began in February 2009, Southwest announced on August 21, 2009 that it would begin rolling out in-flight wi-fi Internet connectivity via Row 44's satellite-broadband based product. Southwest began adding Wi-Fi to its aircraft in the first quarter of 2010. The airline began testing streaming live television in the summer of 2012 and video on demand in January 2013. All 737-700s and -800s are now equipped with Wi-Fi, streaming live television, Beats audio and video on demand. Starting in May 2015 customers can also access free eBooks.

Passengers board a new 737-800 jetliner with the new Evolve Interior at Sacramento International Airport

Evolve interior

On January 17, 2012, Southwest introduced a plan to retrofit its fleet with a new interior. Improvements include a modern cabin design, lighter and more comfortable seats made of eco-friendly products, increased under-seat space, new netted seatback pockets to provide more knee room, a new fixed-wing headrest and improved ergonomics. All Boeing 737-700s and -800s and 78 737-300s have the Evolve Interior. Though not originally planned, because of space saved, Southwest was able to fit an extra row of seats on its planes.

Sponsorships

Southwest Airlines is the official airline for four Major League Baseball teams, the Texas Rangers, the Baltimore Orioles, the Milwaukee Brewers, and the San Diego Padres. The Los Angeles Dodgers used to be their airline sponsor; they signed a deal with United in 2015. Also it serves as a sponsor for the NBA, especially the Houston Rockets and it was the official airline for the Super Bowl.

Rapid Rewards

Southwest first began to offer a frequent-flyer program on June 20, 1987, calling it The Company Club. Unlike competitors' programs which were based on miles flown, The Company Club credited for trips flown regardless of distance. Southwest Airlines renamed its frequent flyer program Rapid Rewards on April 25, 1996.

The original Rapid Rewards program offered one credit per one-way flight from an origin to a destination including any stops or connections on Southwest Airlines. When 16 credits were accumulated in a 24-month period, Southwest awarded one free round-trip ticket that was valid for 12 months.

On March 1, 2011, Rapid Rewards changed to a points system based on ticket cost. Members earn and redeem points based on a three-tier fare scale multiplier and the cost of the ticket. Changes also included no blackout dates, seat restrictions or expiring credits. It also adds more options to use points.

Incidents and accidents

Southwest Airlines Flight 1248 runway overrun at Chicago Midway International Airport

Southwest Airlines has never had any fatalities as a result of a crash. Southwest Airlines incidents include 2 deaths (1 non-passenger death on the ground, 1 accidental passenger death in the air) and 8 accidents (including 2 aircraft hull losses). The airline was considered among the 10 safest in the world in 2012.

Controversies

See also: Kevin Smith feud with Southwest Airlines and Access Now v. Southwest Airlines

On June 22, 2011, a March 25 recording of an in-flight transmission of Southwest pilot Captain James Taylor apparently unintentionally broadcasting a conversation with his co-pilot was released to the press. The conversation was peppered with foul language directed at gay, overweight and older flight attendants. According to Southwest, the pilot was reprimanded, temporarily suspended without pay and received diversity education before being reinstated. Captain Taylor also sent an e-mail apology to all of Southwest's employees, especially the crew members who were criticized.

On 18 November 2015, in two separate incidents, passengers at Midway Airport were allegedly not permitted to fly aboard Southwest Airlines flights when other passengers claimed to be afraid to fly with them because they were speaking Arabic, or appeared to be Muslim. The refusal sparked widespread condemnation on the airline's social media pages and received prominent coverage, in the US and internationally, accompanied by calls for a boycott of the airline. According to The Economist, "in the two Southwest cases, it was the passengers themselves conducting their own vigilante profiling; the airline was merely bowing to their demands."

Electronic address: cshong@swu.edu.cn.AbstractIn the present work, a novel strategy based on overoxidized polyimidazole (PImox) and graphene oxide (GO) copolymer modified electrode was proposed for the simultaneous determination of ascorbic acid (AA), dopamine (DA), uric acid (UA), guanine (G) and adenine (A). The copolymer was characterized by the scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS). Due to the synergistic effects between PImox and GO, the proposed electrode exhibited excellent electrochemical catalytic activities and high selectivity and sensitivity toward the oxidation of AA, DA, UA, G and A. The peak separations between AA and DA, AA and UA, UA and G, and G and A were 140mV, 200mV, 380mV and 300mV, respectively. The linear response ranges for AA, DA, UA, G and A were 75-2275μM, 12-278μM, 3.6-249.6μM, 3.3-103.3μM and 9.6-215μM, respectively, and corresponding detection limits were 18μM, 0.63μM, 0.59μM, 0.48μM and 1.28μM.

By exploiting acridine orange (AO) dyes-graphene as a nanofilter and nanoswitch and the ability of graphene to interact with DNA with different structures, our approach can efficiently distinguish, quantitatively detect target analytes. In vitro assays with G4DNA demonstrated increases in fluorescence intensity of the AO-rGO system with a linear range of 16-338nM and a detection limit as low as 2.0nM. The requenched fluorescence of the G4TBA-AO-rGO system has a non-linear response to Fenton reagent. But this requenching reduces the fluorescence intensity in a manner proportional to the logarithm to the base 10 of the concentration of Fenton reagent in the range of 0.1-100μM and 100-2000μM, respectively. Furthermore, we develop a novel and intelligent sensing method based on fuzzy logic which mimics human reasoning, solves complex and non-linear problems, and transforms the numerical output into the language description output for potential application in biochemical systems, environmental monitoring systems, and molecular-level fuzzy logic computing system.

Electronic address: yuanruo@swu.edu.cn.AbstractA novel electrochemiluminescence (ECL) enzyme biosensor for the ultrasensitive detection of cholesterol was designed based on a bi-pseudoenzymatic reaction to generate a coreactant of peroxydisulfate for signal amplification. In this work, hemin-functionalized graphene (hemin-GR) was synthesized and used to immobilize cholesterol oxidase (COx) to construct an ECL biosensor for cholesterol. When cholesterol was added to the detection solution, COx catalyzed the oxidation of cholesterol to generate H2O2, which could be further catalyzed by hemin to produce O2 as the coreactant in the peroxydisulfate system for signal amplification. The linear range for cholesterol detection was 3.3-1,500nM, with a lower detection limit of 1.0nM (signal to noise ratio=3). Therefore, the detection limit and sensitivity of the biosensor were improved. This novel strategy offers advantages of simplicity, improved sensitivity, good selectivity, and repeatability, and therefore, holds promise for use in sensitive bioassays for clinical determination of cholesterol levels.

• Porous platinum nanotubes labeled with hemin/G-quadruplex based electrochemical aptasensor for sensitive thrombin analysis via the cascade signal amplification.

• Sun A1, Qi Q2, Wang X3, Bie P4.Author information 1Department of Chemistry and Chemical Engineering, Xinxiang University, Xinxiang 453000, PR China. Electronic address: ailisun77@gmail.com.2Southwest Hospital & Institute of Hepatobilitary Surgery, the Third Military Medical University, Chongqing 400038, PR China; Department of General Surgery, the 371th Hospital of PLA, Xinxiang 453000, PR China.3Department of Chemistry and Chemical Engineering, Xinxiang University, Xinxiang 453000, PR China.4Southwest Hospital & Institute of Hepatobilitary Surgery, the Third Military Medical University, Chongqing 400038, PR China.AbstractFor the first time, a sensitive electrochemical aptasensor for thrombin (TB) was developed by using porous platinum nanotubes (PtNTs) labeled with hemin/G-quadruplex and glucose dehydrogenase (GDH) as labels. Porous PtNTs with large surface area exhibited the peroxidase-like activity. Coupling with GDH and hemin/G-quadruplex as NADH oxidase and HRP-mimicking DNAzyme, the cascade signal amplification was achieved by the following ways: in the presence of glucose and NAD(+) in the working buffer, GDH electrocatalyzed the oxidation of glucose with the production of NADH. Then, hemin/G-quadruplex as NADH oxidase catalyzed the oxidation of NADH to in situ generate H2O2. Based on the corporate electrocatalysis of PtNTs and hemin/G-quadruplex toward H2O2, the electrochemical signal was significantly amplified, allowing the detection limit of TB down to 0.15pM level. Moreover, the proposed strategy was simple because the intercalated hemin offered the readout signal, avoiding the adding of additional redox mediator as signal donator. Such an electrochemical aptasensor is highly promising for sensitive detection of other proteins in clinical diagnostics.
