Spirit Airlines' bankruptcy exit plan is under renewed pressure after a sharp rise in jet fuel prices undermined key assumptions behind its restructuring. The ultra-low-cost carrier built its turnaround on fuel costs averaging about $2.24 per gallon in 2026 and $2.14 in 2027, but jet fuel prices are now around $4.24 a gallon, roughly double the level assumed in its projections. J.P. Morgan estimates that if fuel stays near current elevated levels, Spirit's forecast 2026 operating margin could deteriorate to about negative 20%, adding about $360 million in incremental costs, more than the airline's year-end unrestricted cash.

Why it matters

Spirit's bankruptcy exit plan relies heavily on lower fuel prices, and the recent surge in jet fuel costs threatens to undermine the airline's turnaround strategy. If higher costs make it harder for Spirit to reach agreements with creditors and other stakeholders, it could be forced to liquidate, which would have significant implications for the airline industry and the communities it serves.

The details

Spirit Airlines built its restructuring plan, known as 'Project Soar,' on the assumption of lower fuel prices. The plan calls for shrinking the airline to about 76 aircraft by mid-August 2026, reducing aircraft-related debt and focusing on routes with stronger revenue potential. However, creditors have pushed back, arguing that the plan leaves little margin for error and that the airline's projections do not adequately account for the impact of sustained high fuel prices.

  • In mid-April 2026, jet fuel prices were around $4.24 a gallon, roughly double the level assumed in Spirit's restructuring projections.
  • Spirit's March 2026 filing says the airline has responded to the fuel spike with fare increases and capacity cuts.

What they’re saying

“The recent increase in fuel prices would have an 'immediate and substantial negative impact' on results and warned that if higher costs make it harder to reach agreements with creditors and other stakeholders, it could be forced to liquidate.”

— Spirit Airlines

“Higher fuel prices represent 'an entirely new and unbudgeted strain' not reflected in the projections, raising questions about whether the plan is feasible.”

— Citibank, Administrative Agent

What’s next

Spirit Airlines is currently seeking court approval for its second restructuring plan in less than a year. The judge overseeing the case will need to weigh the airline's revised projections and the concerns raised by creditors about the feasibility of the plan given the sustained high fuel prices.

The takeaway

The surge in jet fuel prices has put significant strain on Spirit Airlines' bankruptcy exit plan, raising the risk of liquidation if the airline is unable to reach agreements with creditors and other stakeholders. This highlights the vulnerability of ultra-low-cost carriers to external shocks and the challenges they face in maintaining profitability in a volatile industry.
