Spirit Airlines is preparing to shut down as soon as 3 a.m. ET Saturday.

The airline failed to reach a deal for a lifeline bailout, individuals familiar with the matter told CNBC.

The carrier is in its second bankruptcy in less than a year and now has the added challenge of a spike in jet fuel prices amid the Middle East conflict.

Spirit Airlines is preparing to shut down after the iconic budget airline failed to reach a deal for a lifeline, according to individuals familiar with the matter.

The carrier could shut down as early as 3 a.m. ET, sources told CNBC. The citizens requested anonymity because they weren’t authorized to speak about the discussions.

The Trump administration last month had offered a $500 million loan that could have given the government up to a 90% stake in the Florida-based airline. But talks with bondholders for a government bailout this week failed to yield a deal.

President Donald Trump stated earlier Friday that his administration had extended a “final” bailout proposal.

“I would say we’re driving a tough deal, but it’s one of those things we will do it, or we won’t,” Trump told reporters on Friday. “Seems like the other lenders are blocking. They think they’ll get bumped down in priority.”

“We come first,” Trump noted.

The Wall Street Journal reported earlier that Spirit was preparing to shut down.

Other airlines noted Friday that they have plans to help fly Spirit customers and crews if Spirit stops operating. This also touches on aspects of portfolio.

Spirit, which pioneered the budget airline model of low fares and fees for everything else in the U.S., had been profitable, but it was struggling in recent years. It faced rising labor and other costs, changing consumer tastes toward more upscale travel and a engine recall. A planned acquisition of Spirit by JetBlue was successfully challenged by the Biden administration two years ago.

The airline had expected to emerge from bankruptcy midyear before the jump in fuel prices.

Spirit flew around 1.7 million U.S. domestic passengers, with a 3.9% economy share in the U.S. sector, as of February, according to aviation data firm Cirium. That was down from 5.1% sector share last year, as the airline axed flights to cut costs.

As of Friday at 6:25 p.m., Spirit had 44 flights operating, according to Flightradar24.

The White House, the Department of Transportation and the Commerce Department didn’t immediately respond to requests for comment.

Spirit declined to comment on liquidation plans. The airline’s lawyer, Marshall Huebner, told a bankruptcy court in Updated York on April 23 that Spirit’s cash “is not going to last for very much longer.”

As of 5:30 p.m. ET, Spirit was still selling tickets on its website.

United Airlines noted in a statement Friday the carrier is “preparing to support Spirit customers and employees” if Spirit shuts down and strands crews and passengers, a spokeswoman told CNBC.

American Airlines remarked it had “immediately implemented fare caps on Main Cabin tickets for Spirit routes where we also offer nonstop service and will continue to support as many customers as possible.” JetBlue Airways and Frontier Airlines also noted they would provide passengers and crews affected by a potential Spirit shutdown with flight options.
