Getting money back from a US airline for a delayed flight is about to get harder. The Department of Transportation has published a rule, effective October 19, 2026, that reclassifies ten types of delay events as outside an airline's control — and "within the carrier's control" is precisely the trigger for compensation.
The change implements Section 511(b) of the FAA Reauthorization Act of 2024 and tweaks how carriers report the causes of cancellations and delays. The events newly off the hook are a mixed bag: aircraft cleaning after a passenger dies onboard, damage from extreme weather or sabotage, cyber-attacks, third-party system failures, removing an unruly passenger, and airport closures caused by volcanic ash or wind shear. Not everything is forgiven, though. Airlines are still on the hook for the classics — fueling problems, weight and balance errors, and crew legality issues like rest requirements.
The DOT itself, in the rule's own language, calls this "a transfer of value from consumers back to air carriers" and concedes it will mean less compensation overall. That's a notable admission, given how thin US passenger rights already are compared with the EU, the UK, or Canada, where payouts for delays are mandated by law. In America, airlines set their own compensation policies in their Contracts of Carriage, and there's no federal requirement to pay anything for a delay or cancellation at all. What travelers usually get — hotel rooms, meal vouchers, rebooking — is a voluntary industry commitment, offered only when the airline judges itself at fault. The DOT's Airline Customer Service Dashboard applies some public pressure, but the new reporting categories tip that judgment call further in the airlines' favor.
There is one bright spot travelers should know about. A 2024 rule still requires airlines to issue a full, automatic, prompt refund — in the original form of payment, whether cash or miles — if a flight is canceled or delayed by more than three hours (six for international), as long as you don't accept an alternative like rebooking. But even that protection now hinges on the cause being deemed the airline's fault, and the goalposts have just moved.
One partial workaround: flying a foreign carrier on an international route keeps you under that carrier's stronger home-country rules. Foreign airlines can't operate US domestic flights, so this only helps on long-haul itineraries. For everything else, the practical takeaway is to document delays carefully, request rebooking or a refund rather than a voucher when you qualify, and read your airline's Contract of Carriage before you fly. After October 2026, expect carriers to lean on the new exclusions more often — so knowing what still counts as their fault is worth the five minutes it takes.
