The collapse of Spirit Airlines and what it reveals about the future of affordable aviation
Spirit Airlines ceased operations earlier this month, marking the first major American airline shutdown in nearly 25 years, a signal of how fragile the global aviation sector has become.
Spirit Airlines ceased operations last Saturday. It is the first major American airline to shut down in nearly 25 years, and its causes say a great deal about the delicate moment the global aviation sector is navigating.
The immediate cause is well known: jet fuel prices have nearly doubled since the start of the conflict in Iran. Spirit had projected fuel costs at USD 2.24 per gallon for 2026. By April, the price had reached USD 4.51. No restructuring plan survives that kind of shock when operating margins were already at their limit. Airlines operate, in the best of times, with profitability between 3% and 6%. There is no buffer to absorb a swing of that magnitude.
But the structural cause is older. Spirit had not turned a profit since 2019. The ultra-low-cost model, which worked well throughout the 2010s, lost traction after the pandemic. Passengers began prioritizing comfort and experience. The major carriers responded with basic economy fares that competed directly with low-cost carriers, stripping them of their primary selling point: price.
What makes the moment even more concerning is that Spirit may not be the last. David Neeleman, founder of JetBlue Airways, publicly stated this week that the airline may be heading toward bankruptcy. With fuel at USD 4.50 per gallon, JP Morgan projects a USD 1.3 billion loss for JetBlue in 2026. JetBlue is not a traditional low-cost carrier. It has a well-regarded service proposition. But it operates at regional airports, with smaller aircraft and competitive pricing. And no major American airline has shown interest in acquiring it.
What is at stake, beyond the survival of specific carriers, is the competitive structure of the entire sector. In the United States, four airlines already control around 80% of available flights. With Spirit gone and JetBlue under pressure, concentration is likely to increase. In markets where air transport supply is largely inelastic, less competition historically means higher fares and fewer options for passengers. This is not a forecast. It is a market mechanism.
That equation has direct implications for Brazil, today the tenth largest corporate travel market in the world and home to the second largest airport infrastructure on the planet, with more than 2,400 airports. The Brazilian market has long operated under a de facto oligopoly, with a handful of carriers controlling supply across a country of continental dimensions. The memory of the collapse of Varig, Transbrasil, and more recently Avianca Brasil, shows that the domestic sector is not immune to these movements.
The risk in Brazil goes beyond the financial turbulence of individual carriers. If the number of players shrinks further in a market where per capita air travel penetration is still low, flying could become economically unviable for a significant portion of the population. The airplane, which in recent years had begun to shed its status as a privilege of the few, could return to being exactly that. And the consequences extend far beyond tourism: they affect regional development, economic integration, and the mobility of workers in a country where air travel, on many routes, is the only reasonable transportation alternative.
The collapse of Spirit is a signal. Not only about the risks of a specific business model, but about the fragility of a sector the entire world depends on to function, and which, even so, rarely receives the strategic attention it deserves.
