The defunct discounter’s collapse did not happen overnight, but rather after Spirit exhausted all options to re-establish profitability.
Two bankruptcies, sweeping strategic overhauls, aggressive fleet- and schedule-slashing, multiple tie-up attempts and a last-ditch government rescue effort were not enough to save Spirit Airlines from a grueling slow-motion implosion that is already reshaping the US airline market.
Following a final flight from Detroit to Dallas on 2 May, the Florida-based ultra-low-cost carrier (ULCC) closed a 34 year-era of operating bargain flights across the USA and to near-international destinations in Latin America. So concluded a protracted phase in which the carrier attempted to shrink short-term, then potentially resume growth later. The company had forecast generating cash from operations by October and turning a modest profit for the full year of 2027.
Myriad factors contributed to Spirit’s demise, though the recent surge in jet fuel prices – precisely as Spirit was attempting to emerge from its second Chapter 11 bankruptcy in 16 months – effectively delivered a knockout punch to an airline that was already on the ropes.
“The wind-down follows the company’s extensive and comprehensive efforts to restructure the business and pursue transactions to strengthen Spirit’s financial position and create a sustainable path forward,” the airline said.
“Unfortunately, despite the company’s efforts, the recent material increase in oil prices and other pressures on the business have significantly impacted Spirit’s financial outlook.”
Chief executive Dave Davis says that Spirit had reached an agreement with bondholders in March that would have allowed it to carry on as a standalone business. “However, the sudden and sustained rise in fuel prices in recent weeks ultimately has left us with no alternative but to pursue an orderly wind-down of the company.”
Spirit’s network covered about 3.9% of the US airline market, down from more than 5% just a year earlier, according to aviation analytics firm Cirium, reflecting its diminished position following dramatic capacity cuts.
Spirit’s ungainly demise is a sharp contrast with the 2010s, which saw it and primary competitor Frontier Airlines become the fastest-growing airlines in the country. The ULCCs quickly scaled their respective Airbus narrowbody fleets, largely by using sale-leaseback deals. Both targeted the most price-sensitive air travelers with bare-bones baseline products and add-on ancillary fees. They also effectively undercut major airlines’ airfares, drawing fierce competition from the top of the market.
But as with many things, the collapse can be traced to Covid-19, or rather the post-pandemic consumer shift away from discount airline seats. While Spirit followed the broad industry trend of introducing more premium-oriented products to court high-paying customers, some airline industry observers believed the effort was too little, too late.
The discounter’s generally poor reputation with the flying public made any attempt to attract business and high-end leisure travelers a difficult sell. New revenue streams trickled in, but not enough to counter big–picture changes in consumer spending.
Meanwhile, Spirit continued, until relatively recently, to fly its large Airbus narrowbody jets into the largest US metro areas, competing head-to-head with the likes of American Airlines, Delta Air Lines and United Airlines. Such a strategy proved brutally difficult as those industry-shaping giants dialed in discount products of their own, pressuring ULCCs from above.
Compounding those problems, Spirit was among the hardest-hit carriers in the Americas by Pratt & Whitney’s recall of several thousand PW1100G geared turbofan (GTF) engines. Those latest-generation powerplants have required costly and time-consuming repairs for manufacturing-related durability issues, keeping thousands of Airbus A320neo-family jets out of revenue-generating service globally.
Spirit had dozens of grounded jets on a rolling basis dating back to 2023, creating a significant drag on the carrier’s already-challenged financial performance. With odd exceptions, it took heavy quarterly losses dating back to the US airline’s recovery from Covid.
“The long-term debt load had ballooned to over $8 billion at the time of its second bankruptcy filing,” Bill Swelbar, an airline analyst with the Swelbar-Zhong Consultancy, told FlightGlobal in March. “Borrowing to grow only to lose even more money is what landed them in bankruptcy twice.”
The company took drastic action. Last year, the airline exited “over 200 underperforming markets and reallocated capacity into areas of strength”, Spirit said in its annual 10K filing with the US Securities and Exchange Commission. It also slashed its aircraft fleet, in turn reducing balance sheet debt and lease obligations.
After beginning a second Chapter 11 restructuring in late August, Spirit began a dramatic capacity reduction plan to right-size capacity to demand, rejecting the leases of dozens of Airbus jets. Throughout that process, the company sought to reduce its GTF recall burden by returning a disproportionate percentage of A320neo-family jets. (Spirit also struck significant compensation deals with P&W to partially offset the cost of lost aircraft productivity.)
On the network side, Spirit’s sweeping restructuring plan involved cutting its fleet by nearly two-thirds and trimming its network to focus on four core cities – Fort Lauderdale, Orlando, Detroit and the New York City area via Newark Liberty International airport. In another pivot, Spirit tried to adopt an Allegiant Air-type model targeting underserved secondary cities and employing a flexible schedule to match surges in demand. Arguably, neither initiative had enough time to show any success before Spirit felt the fuel shocks emanating from the Middle East.
Since the US and Israel launched their war in Iran on 28 February, airlines have struggled with increased fuel-price volatility as a result of the Strait of Hormuz’s closure and ripple effects on the world’s oil supply, squeezing low-cost operators hardest.
It is debatable whether Spirit could have survived as a standalone airline if it had emerged from bankruptcy this spring as planned. But the fuel cost surge effectively ensured that it could not stagger along without assistance.
US President Donald Trump publicly considered directing the US government to purchase up to a 90% stake in Spirit, reportedly at a value of about $500 million. But those talks reportedly fell apart as Spirit’s creditors balked at the proposed conditions.
OPPORTUNITIES AND ALARMS
Spirit’s withdrawal has created in the vacuum, which the discounter’s competitors – and failed combination partners – have quickly moved to fill. Frontier and JetBlue Airways, along with other low-cost carriers, are among the US airlines that stand to benefit most.
James Dempsey, Frontier’s CEO, argues that the Denver-based discounter is the “best-positioned” to fill Spirit’s previous place in the market, as Frontier overlapped with Spirit on more than 100 routes. It will target another nine former Spirit markets this summer, including new flights to Dallas, Detroit, Fort Lauderdale, Las Vegas and Orlando.
The airlines shared so much network space, many observers felt like a Frontier-Spirit tie-up made the most sense on paper. In fact, Spirit considered such an arrangement at several junctures, but ultimately spurned Frontier’s advances.
Now, Frontier is eyeing Spirit’s holdings, such as aircraft and airport gates, and take-off and landing slots.
“We will look at assets that come out during that wind-down,” Dempsey says, insisting that Frontier will stay “disciplined” regarding any emerging growth opportunities. Spirit’s aircraft would be a natural fit for Frontier, which also operates an all-A320-family fleet.
Overall, Frontier expects a revenue-per-available-seat-mile (RASM) gain of 3-5 percentage points in Spirit’s former market.
While opportunities have arisen from Spirit’s shutdown, alarm bells are also ringing for discounters operating similar models. Avelo Airlines CEO Andrew Levy told FlightGlobal that elevated fuel prices have exposed competitive disparities created partly by US government decisions, including Covid-era bailouts and decades of consolidation approval.
Avelo is among several “value airlines” that continue seeking financial support from the US government to offset high fuel costs. Federal authorities have not moved to create their requested $2.5 billion “liquidity pool”, however.
“If they want to have a sustainable low-fare segment of the marketplace, then it’s very possible they may need to consider doing some things they might not naturally want to consider,” Levy says.
While the US government has long been lenient with major airline mergers, it did not look favourably upon JetBlue’s $3.8 billion bid to acquire Spirit, which the US Department of Justice (DOJ) blocked in January 2024.
Many observers have pointed to the US Department of Justice blocking that deal based on competitive concerns as the source of Spirit’s acute struggles. The Trump administration, for example, has laid Spirit’s collapse at the feet of Trump’s predecessor Joe Biden, whose DOJ blocked the JetBlue-Spirit tie-up.
While the combination would have saved Spirit from its eventual collapse, the post-combination company would have faced many of the same issues – GTF-related aircraft groundings, eroding cost advantages and soaring debt. Notably, JetBlue has also grappled mightily with the increased cost of jet fuel and is reportedly seeking to be acquired by a larger competitor.
The New York-based leisure carrier added routes to 11 new cities out of Fort Lauderdale, formerly Spirit’s main hub, following Spirit’s final flight on 2 May.
Though JetBlue undeniably stands to gain from the new market opportunities, airline president Marty St George expressed sympathy for the pilots, flight attendants and other employees affected by Spirit’s collapse in a recent LinkedIn post, waxing poetic about the difficulties of the discount airline sector.
“Even if your company does not go out of business, employee furloughs are not uncommon,” he says. “Many of us have gone through this pain and more importantly we know it could just as easily be us the next time.”
