Spirit Airlines just officially closed down. What happens to my outstanding ticket?

Spirit Airlines really said “final boarding call” and meant it.

Over the weekend, the ultra-low-cost carrier abruptly shut down, canceling every flight in its network and leaving thousands of travelers stranded, confused or suddenly scrambling to salvage trips that, hours earlier, were still very much on. Some people found out mid-journey. Others showed up at the airport only to discover their flight (and the airline itself) no longer existed.

For the airline, the end came down to finances. “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,” said CEO Dave Davis in a statement, calling the shutdown “tremendously disappointing.”

If you had a Spirit ticket sitting in your inbox, the situation is a mix of surprisingly straightforward and wildly uncertain.

On the straightforward side: refunds. If you paid with a credit or debit card, there’s a good chance your money is already on its way back. Spirit says those refunds are being processed automatically and in many cases, they were initiated almost immediately after the shutdown (though it can take a few days to land in your account). Federal officials have also said that funds for unused tickets were held in reserve, which should help ensure those payments actually go through.

Now for the messier part. If you booked using vouchers, flight credits or Free Spirit miles, you’re no longer dealing with a standard refund—you’re dealing with bankruptcy. Those claims will be sorted out through the airline’s court proceedings, which can take months and don’t guarantee you’ll see any money at all. In many past airline collapses, travelers in that category have ended up at the back of the line.

While the refund question is one thing, the rebooking scramble is another. With thousands of flights suddenly gone, other airlines have stepped in with limited “rescue fares” and temporary price caps, but availability is tight and prices on some routes have already jumped. Stranded travelers have reported paying significantly more than their original tickets would have cost just to get to their destination.

There’s also an extra wrinkle in the form of third-party bookings—where you’ll likely need to go through your travel agent for any refund requests.

In short, if your trip disappeared this weekend, you’re not alone. Depending on how you paid, your money might already be on its way back—or tied up in a process that’s only just beginning.
