Spirit Airlines was an American ultra-low-cost airline, headquartered in Dania Beach, Florida. It operated scheduled flights throughout the United States, the Caribbean, and Latin America. In 2023, it was the seventh-largest passenger carrier in North America and the region's largest ultra-low-cost carrier before ceasing flight operations on May 2, 2026.
Spirit was founded in 1964 as a trucking company that pivoted to operating charter flights in 1983 before finding success by bringing the ultra-low-cost carrier model to the United States, offering very low base fares supplemented by additional fees for nearly every service. This approach allowed it to expand rapidly by attracting price-conscious leisure travelers, but also left it highly sensitive to cost pressures. By the 2020s, its business model came under increasing pressure as the legacy carriers introduced basic economy fares, eroding its price advantage, while labor, aircraft, and operating costs increased.
In 2022, Frontier Airlines reached an agreement to acquire Spirit but was outbid by JetBlue; the JetBlue merger was blocked in January 2024 by the Biden administration, leaving Spirit independent but weakened financially. Spirit filed for Chapter 11 bankruptcy protection in November 2024 and briefly emerged from restructuring in early 2025, but filed for Chapter 11 again in August amid mounting losses and debt. In May 2026, the airline suddenly ceased operations after bailout negotiations with the second Trump administration failed; Spirit said that the sharp rise in jet fuel prices linked to the 2026 Iran war made its low-cost business model unsustainable. Flights ended with little advance notice; operations were halted within a day of the announcement. The airline now plans to file for Chapter 7 bankruptcy.

History
From Clippert Trucking Company to Charter One Airlines
The company began in 1964 as Clippert Trucking Company. In 1974, it changed its name to Ground Air Transfer, Inc. In 1983, Ned Homfeld founded Charter One Airlines in Macomb County, Michigan, as a Detroit-based charter tour operator offering travel packages to destinations including Atlantic City, Las Vegas, and the Bahamas.
1990s: Spirit Airlines, headquarters moved to Florida
In May 1992, the company introduced McDonnell Douglas DC-9 and McDonnell Douglas MD-80 jet aircraft and changed its name to Spirit Airlines. Spirit expanded from charter operations into scheduled service on June 1, 1992, with flights between Detroit and Atlantic City. Flights from Boston and Providence to Atlantic City followed on June 15. Through 1994, Spirit added scheduled service to Orlando, Fort Lauderdale, and St. Petersburg, Florida, Atlantic City and Fort Myers, Florida, and Philadelphia.
Spirit initially maintained its headquarters in the Kennedy Building in Eastpointe, Michigan, formerly East Detroit, in Metro Detroit. In December 1999, the airline moved its headquarters to Miramar, Florida. Before selecting Miramar, Spirit also considered Atlantic City and Detroit.
In the summer of 1994, Spirit canceled tickets for 1,400 customers following an overbooking incident. According to the airline, the issue resulted from incorrect instructions provided to travel agents, which caused some tickets to be treated as invalid despite customers having paid for them. In response to criticism, Spirit stated that it would accommodate all ticketed passengers, including by booking them on competing airlines if necessary.
In 1996, Janet Patton became Spirit Airlines' first female pilot. She became the airline's first female captain in 1998.
2000s: Baldanza, ultra low-cost carrier, Caribbean
In 2005, Ben Baldanza was hired as president. Following an investment by Indigo Partners in 2006, Baldanza became CEO and assumed a larger role in the airline's operations and strategy. Under Baldanza, Spirit adopted an ultra-low-cost carrier business model modeled in part on Ireland's Ryanair, emphasizing very low base fares supplemented by additional fees for nearly every service.
While strategy received significant media criticism, the airline continued to expand its customer base and revenue from optional services. Spirit also became known for advertising campaigns and promotional fares that used provocative humor and double entendres, including its "MILF" promotion, which stood for "Many Islands, Low Fares".
Spirit rapidly expanded its network throughout the 2000s, including service to destinations in the United States and the Caribbean, and filed applications for additional international routes, but the airline's focus on high aircraft utilization in an effort to keep operating costs down contributed to weak operational reliability and limited recovery options during disruptions.
The airline also faced regulatory and labor developments, including a 2000 Federal Aviation Administration fine for aircraft marking and placarding violations, and a 2010 pilot strike that temporarily grounded operations from June 10 to 18.
2010s: Increased competition, two CEO changes
Spirit Airlines introduced a fee for carry-on baggage in 2010, the first U.S. airline to do so. Other U.S. ultra-low-cost carriers, including Allegiant Air and Frontier Airlines, later adopted similar charges. In 2012, the airline faced public criticism after declining to refund a fare to a terminally ill military veteran who had purchased a nonrefundable ticket. Spirit later issued an apology, refunded the fare, and made a donation to the Wounded Warrior Project.
During this period, Spirit faced increased competition from basic economy fares introduced by the legacy carriers, which incorporated elements of the ULCC model by offering low base fares supplemented with fees. Delta Air Lines introduced basic economy fares in 2012, and by the end of the decade all of the U.S. legacy carriers had implemented similar fare products. The strategy proved effective, as many passengers shifted toward legacy carriers when basic economy fares were competitively priced, drawn by broader route networks, higher frequency, and perceptions of better reliability and service.
Former AirTran Airways CEO Robert Fornaro succeeded Baldanza as CEO in 2016 and introduced initiatives aimed at improving operational performance and customer service, including collaboration with the Disney Institute. During this period, Spirit continued to expand its network and maintained its ancillary fee-based pricing model. By 2017, Spirit's on-time performance had improved compared with earlier years, ranking among U.S. carriers by that metric. In 2018, the airline began equipping its fleet with Wi-Fi service.
Ted Christie succeeded Fornaro as CEO in January 2019 and led Spirit to make significant capital investment announcements in 2019, including that it would move into a newly built headquarters in Dania Beach, Florida, and acquire 100 new Airbus A320neo family aircraft.
2020s: Decline and bankruptcy
At the start of the COVID-19 pandemic, Spirit Airlines received $334 million in assistance through the Coronavirus Aid, Relief and Economic Security (CARES) Act in the form of grants and loans. However, since CARES Act funds were allocated based on employment levels in mid-2019, companies experiencing rapid pre-pandemic growth, including Spirit, did not receive the same level of support as more stable competitors. The funds were used to support payroll through September 30, 2020. In July 2020, the company announced plans to place 20–30% of employees on furlough beginning in October. Some pilots and flight attendants later accepted voluntary leave or reduced schedules to limit layoffs.
During the post-pandemic recovery, Spirit faced increased competition as legacy carriers expanded basic economy fares and added capacity. Spirit also faced higher labor costs as airlines increased compensation to attract and retain pilots following pandemic-related retirements. The company never posted a profit after 2019.
In August 2023, the airline converted an order for 31 Airbus A319neo into the larger A321neo. Spirit's order had made up a third of all A319neo orders, briefly putting the type's future in question.
In January 2025, Spirit Airlines laid off 200 employees as part of cost reduction measures. In April 2025, Spirit Airlines exited Chapter 11 bankruptcy and appointed Dave Davis as CEO.
Since 2022, various competing low-cost airlines announced plans to acquire Spirit. In February 2022, Frontier Airlines announced its intention to acquire Spirit, pending regulatory approval, with Frontier Airlines stock as the surviving entity. The deal would have made the combined airline the fifth-largest airline in the U.S. In July 2022, Spirit's shareholders rejected Frontier's offer.
In April 2022, JetBlue proposed to acquire Spirit for $33 per share in cash, equivalent to $3.6 billion. In May, Spirit said its board of directors had decided not to consider JetBlue's proposal. According to Spirit Airlines, JetBlue's proposed acquisition would be unlikely to be approved by the U.S. Department of Justice's Antitrust Division, because it would likely believe that an ultra-low-cost carrier being purchased by a higher-fare airline would increase fares for consumers. Spirit noted that the Antitrust Division was looking into JetBlue's strategic partnership with American Airlines for the same reason.
Corporate affairs
Business trends
The key trends for Spirit Airlines were (as of the end of the calendar year):
Ownership
Spirit Airlines, Inc., was a Delaware corporation that was publicly traded on the New York Stock Exchange until its bankruptcy filing in 2024.
Headquarters
In 2019, the airline announced that it would move to new headquarters of up to 500,000 square feet (46,000 m2) in the Dania Pointe development in Dania Beach, Florida, spending $250 million. The airline anticipated the facility would house 1,000 employees. The Dania Pointe headquarters opened for business in April 2024.
Previously, Spirit had been headquartered at 2800 Executive Way, Miramar, Florida, having moved there from its previous Eastpointe location in 1999. As of 2016, there were 600 employees located in the office. Chris Sloan of Airways Magazine stated that the building was "nondescript low slung". Sloan added that the interior, prior to a 2014 renovation, was, "To put it charitably, [...] a dump", but that employees felt ownership over the office.
Following Spirit's closure, the Broward County Board of County Commissioners voted in May 2026 to explore purchasing the building.
On August 13, 2026, DPC HoldCo, an affiliate of Boston-based investment firm, Hill City Capital, bought the Spirit HQ for 93.25 million dollars in cash after the bid submission got accepted as part of the auction hosted on August 11th.
Business model
Under CEO Ben Baldanza, Spirit began a transition to an ultra low-cost carrier, following a fare model involving charging for amenities often included in the base ticket price of traditional carriers. Passengers who wanted to customize their itinerary or seat selection paid an add-on fee for each additional feature, enabling the carrier to earn ancillary revenue in excess of 40% of total revenue. These included having an agent print a boarding pass at check-in versus doing it online or at a kiosk, fees for large carry-on or checked bags, and progressive fees for overweight bags, selected seat assignments, travel insurance and more.
Frequent-flyer program
Spirit Airlines had a three-tier frequent-flyer program called Free Spirit.
Controversy
Spirit Airlines had been the subject of numerous complaints, and punitive actions by the U.S. Department of Transportation (DOT). Most of the claims against the company were for allegations of deceptive advertising practices, customer service, and the airline's charging additional fees at the time of purchase as a matter of policy:
In November 2011, the DOT fined Spirit $43,900 for alleged deceptive advertising practices. The complaint claimed that the airline had been running an advertising campaign which promoted specific discounted fares on billboards, posters, and Twitter, but did not disclose full details of extra fees charged in addition to the advertised rates.
In January 2012, the DOT fined Spirit $100,000 for mishandling complaints related to its treatment of customers with disabilities.
In 2013 and 2015, the DOT received more passenger complaints about Spirit than any other airline. The rate of complaints was "dramatically higher" than the overall rate for the industry.
In February 2018, a 21-year-old passenger flushed her hamster down a toilet in an airport bathroom, after the company refused to let her take the hamster on the flight. The passenger was misinformed by a reservation representative that she could bring the emotional support animal. She said that a flight attendant suggested that she flush the hamster down the toilet, which the airline denied.
On August 3, 2021, Spirit Airlines canceled 40% of its flights, leaving travelers stranded because it had no arrangements with other airlines to book its passengers on other airlines' flights. Spirit Airlines said, "We're working around the clock to get back on track in the wake of some travel disruptions over the weekend due to a series of weather and operational challenges. We needed to make proactive cancellations to some flights across the network, but the majority of flights are still scheduled as planned." By August 10, the schedule was stabilizing.
In June 2023, a passenger was forced to urinate on the floor of a galley after cabin crew persistently denied her bathroom access for over two hours. The flight attendant filmed the incident and called the smell of her urine offensive.
Destinations
Spirit's route network combined extensive domestic service within the United States with international leisure routes across Mexico, Central America, the Caribbean, and South America. International destinations included Cancún, Bogotá, Medellín, Lima, San José, San Juan, and Santo Domingo.
Interline agreements
Spirit had interline agreements with French Bee and Norse Atlantic Airways.
