If a US airline shuts down for good, your ticket usually stops working as a boarding pass, and no law forces other airlines to honor it. Your strongest path to your money back is a credit card chargeback, plus any discounted "rescue fares" rival carriers offer to get stranded passengers home.
When a US airline stops flying for good, your ticket basically turns into a worthless piece of paper. There's no federal program that automatically refunds you or forces a competitor to carry you, so the money you paid is now tied up with a failing company. The good news: most people who paid with a credit card end up getting made whole. You just have to chase it.
One important distinction first. An airline in Chapter 11 bankruptcy is reorganizing and usually keeps flying, so your ticket may still be perfectly good. An airline that fully ceases operations, or files Chapter 7 to liquidate, is the real problem. This page is about that second case, when the planes actually stop.
Sometimes, but they are not required to. In the US there's no rule forcing rival carriers to honor a dead airline's tickets. What often happens instead is that competitors voluntarily offer discounted "rescue fares" or "relief fares" to stranded passengers for a short window after a collapse. That's a goodwill move, not a refund, so you still pay something, just less than a normal last-minute price. Check the failed airline's competitors on your route right away, because these offers can vanish fast.
Work through these in order:
One warning: if you paid by debit card, your protection is weaker and slower, since debit falls under different rules and your cash sits in the creditor line.
Other countries build in more safety nets. In the UK, package holidays booked through an ATOL-licensed seller are covered for a refund or a flight home, and credit card purchases can be protected under Section 75 of the Consumer Credit Act. In the EU, the Package Travel Directive protects trips booked as a package. Flight-only bookings tend to have less protection everywhere, which is exactly why how you paid matters so much.
What this means for you: Pay for flights with a credit card, not a debit card or cash, and keep your booking confirmation and card statement. If your airline folds, sort out a way home first, grab any rescue fare, then file your card dispute quickly. That one habit is what turns "I lost my money" into "I got it all back."
