Effective 28 October 2024, US airlines must automatically refund the original ticket price in cash, to the original payment method, when a flight is cancelled or "significantly changed" (3+ hours domestic, 6+ hours international, airport change, added connection, downgrade) and you do not accept the alternative. Refunds within 7 business days for credit-card purchases and 20 calendar days otherwise. Vouchers only if you affirmatively choose them in writing. No fixed delay compensation like EU261 — but the refund right is automatic and the airline cannot make you ask.
What changed in October 2024
For decades, the US handled airline refunds on an opt-in basis: when an airline cancelled a flight, it usually pushed a travel voucher or "future travel funds" and the passenger had to know to demand cash. That changed when the US Department of Transportation published its final rule on "Refunds and Other Consumer Protections" on 26 April 2024, codified at 14 CFR Part 259. Core provisions took effect 28 October 2024; the rest phased in through 2025.
The rule's three biggest changes:
- Default switched from voucher to cash refund. Cash to the original payment method is the default; vouchers only if the passenger affirmatively elects them in writing.
- "Significant change" got a legal definition. Previously airlines could decide what counted as significant. The rule pinned it down at the federal level.
- Refunds are now automatic. The airline must initiate the refund without the passenger having to request it.
The rule applies to US-flag and foreign carriers operating to and from the United States, covers tickets purchased directly from the airline as well as through online travel agents and traditional travel agents, and extends to ancillary services as well as base fares.
What counts as a "significant change"
Under 14 CFR §259.5(b)(1), the following changes are significant enough to trigger your refund right if you choose not to accept the alternative:
| Change | Threshold |
|---|---|
| Domestic flight delay | 3+ hours in departure or arrival |
| International flight delay | 6+ hours in departure or arrival |
| Departure or arrival airport change | Any change |
| Added connection | Any added connection |
| Connection airport change | Change to a different connecting airport |
| Downgrade of service class | Any downgrade (also triggers an automatic fare-difference refund) |
| Aircraft accessibility change | A change that affects a passenger with a disability's ability to use the aircraft |
If any of these happens and you elect not to accept the airline's alternative — including not boarding the rescheduled flight — the airline owes a full refund of the ticket and any unused ancillary services automatically. You do not need to ask; the airline must initiate.
How and when the refund must be issued
The form, speed and method are all specified:
- Method: the original payment method. A flight paid by Chase Visa goes back to the Chase Visa. Cash purchases go back as a check or equivalent.
- Form: the full original fare in actual money — not vouchers, not travel credits, not "future travel funds." Vouchers are only lawful if you choose them in writing.
- Speed: within 7 business days after the refund obligation arises for credit-card purchases, and within 20 calendar days for cash, check, debit card or other payment methods.
- Amount: the full ticket price plus the value of any unused ancillary services (paid seat selection, baggage fees, in-flight Wi-Fi that the airline didn't deliver, paid lounge access on a cancelled segment).
Ancillary service refunds
The 2024 rule made ancillary refunds explicit for the first time. The airline must refund:
- Baggage fees if your checked bag is significantly delayed (defined as 12+ hours for domestic, 15–30 hours for international depending on flight length)
- Baggage fees if your bag is lost outright
- Paid seat-selection fees if you do not get the seat you paid for
- Wi-Fi fees if the service didn't work
- Lounge access fees on a segment that didn't operate
- Any other ancillary you paid for but didn't receive
These are also automatic — the airline must initiate, not wait for you to claim. If they don't, file a DOT complaint at transportation.gov/airconsumer/file-consumer-complaint.
The Airline Cancellation and Delay Dashboard
The DOT also maintains the Airline Cancellation and Delay Dashboard, which publishes each US carrier's own commitments during controllable delays — meaning delays caused by the airline (mechanical issues, crew availability, etc.), not weather or ATC. As of 2026, every major US airline guarantees:
- Free meal vouchers for delays of 3+ hours
- Complimentary hotel for overnight controllable delays
- Ground transportation between the airport and the hotel
- Free rebooking on the next available flight
Several carriers (Alaska, JetBlue, American, Delta, United, Southwest, Hawaiian) also commit to cash compensation for significant controllable delays — typically $75–$200 in travel credit, though some have moved to cash. These airline-specific commitments are binding under DOT enforcement once published. The dashboard makes them comparable in one place.
What the US DOT rule does NOT do
Three points to keep clear:
- No fixed delay payout. Unlike EU261 (€250–€600) or UK261 (£220–£520), the US has no statutory cash compensation for being delayed. The refund only kicks in if you don't fly. If you accept the rebooking and arrive late, you get nothing from the DOT — but check the airline's dashboard commitment.
- Doesn't pay for incidental expenses. No statutory duty-of-care equivalent. Meals, hotel and transport during a delay come from the airline's own commitments (per the dashboard) or from your travel insurance — not from federal law.
- Doesn't apply to flights with no US touchpoint. A London–Paris flight is governed by EU261/UK261, not US DOT, even if you bought the ticket through a US OTA.
Filing a DOT complaint
If an airline fails to automatically refund within the required window, doesn't refund to the original payment method, or improperly tries to substitute a voucher, the right escalation is the DOT itself:
- Try the airline's own refund channel first and document the request and refusal in writing.
- File a complaint at transportation.gov/airconsumer/file-consumer-complaint. There is no fee.
- Include the booking reference, the date of cancellation/change, the amount owed, and copies of correspondence.
- The DOT's Office of Aviation Consumer Protection investigates and can fine airlines for non-compliance. Most complaints are resolved within 60 days.
For ticket purchases on international itineraries, the Montreal Convention 1999 may also apply for consequential losses (missed connections on separate bookings, hotel deposits, etc.) — see our master guide for the SDR limits.
ClaimBox tracks every US DOT refund deadline — free
Add a US flight and ClaimBox watches it on live data. If the airline cancels or significantly changes the schedule, ClaimBox flags the exact refund you're owed, the deadline the airline must meet (7 or 20 days), and pre-writes the DOT complaint if they miss it. You keep 100% of the refund, and the airline pays you directly to your original card.

What is the US DOT automatic refund rule?
The rule, under 14 CFR §259.5 (effective 28 October 2024), that requires US-regulated airlines to automatically refund the original ticket price in cash to the original payment method whenever a flight is cancelled or significantly changed and the passenger does not accept the alternative. It shifted the default from opt-in vouchers to opt-out cash.
What counts as a "significant change"?
A 3+ hour delay on a domestic flight, 6+ hour delay on an international flight, a change of departure or arrival airport, an added connection, a downgrade of service class, or a change that affects accessibility for passengers with disabilities. Any one of these triggers the refund right.
How fast must a US airline issue a refund?
Within 7 business days for credit-card purchases, 20 calendar days for cash, check, debit card or other payment methods. Refunds must go to the original payment method unless you affirmatively request otherwise.
Does the rule require cash compensation for delays like EU261?
No. The US rule guarantees only a refund of the original fare when the passenger doesn't fly, plus refunds of unused ancillary fees. There's no equivalent of EU261's €250–€600 fixed delay payout. Many US carriers offer their own meal/hotel/credit benefits during controllable delays — tracked on the DOT's Cancellation and Delay Dashboard — but those are airline policy, not statutory.
Can the airline give me a voucher instead of a refund?
Only if you explicitly choose one in writing. Cash refund to the original payment method is the default under 14 CFR §259.5. Vouchers, travel credits and "future travel funds" are only permissible when the passenger affirmatively elects them.
