US DOT $US airline refund rules: automatic refunds, significant changes and credits

Checked 15 Sep 2026·13 min read · 4 tables

A canceled flight, or one that lands 3 hours or more late on a domestic trip (6 hours or more on an international one), gets you the fare back under 14 CFR Part 260 unless you accept the airline’s alternative. The DOT flight refund rules below set the triggers and the payment deadlines, then the limits on travel credits. A refund returns what you paid. It is not compensation: for domestic itineraries, the DOT says airlines are not required to compensate passengers whose flights are delayed or canceled. What airlines commit to during a disruption is on the delayed or canceled flight page, and the US DOT hub links every other federal rule. The 24-hour cancellation rule for a booking you cancel yourself has its own page.

#US DOT $When is a US airline refund automatic?

For a canceled or significantly changed flight, 14 CFR 260.6(a) makes a full refund of the fare, taxes and ancillary fees automatic in 3 cases. The airline cancels and offers no alternative. You reject the alternative it offers. Or you do not respond to the offer and do not travel.

When a US airline refund is automatic

Source: 14 CFR 260.2, 260.5(b), 260.6(a); 14 CFR Part 250 — ecfr.gov, checked 2026-09-15.

Only the first two rows return the whole ticket price.

Silence is not acceptance. If the airline offers a rebooking or a credit and you never answer, and you do not fly, the refund is still due: the rule ties the third case to the flight departing, or to the original departure date. Accepting is what closes the automatic refund route. Board the rebooked flight, or say yes to a credit, and none of the 3 cases applies any more.

A passenger report shows how this plays out. In August 2025, u/ramsam1737 posted on r/spiritair that a schedule change notice from Spirit had said: “If you do not board the new flight, a refund of your flight (including your return flight) will be issued automatically to the original form of payment within 7 business days.” The poster did not accept the new itinerary, did not board, and wrote that Spirit was denying the refund as a “no show”. One post is an anecdote, not a pattern. Spirit has since stopped flying, and a carrier that has gone is outside this rule altogether: see airline stopped flying or went bust.

Worked example: a $312 domestic fare including taxes, plus a $35 ancillary fee. The airline cancels and offers a flight the next morning; you buy a seat elsewhere and never reply. The third case applies, and $347 is refundable. Reply to any rebooking offer in writing with “I decline the alternative and request a refund”, so the record shows a rejection rather than silence.

#What counts as a significant delay or change?

3 hours or more on a domestic flight and 6 hours or more on an international one are the time lines in 14 CFR 260.2, for an earlier departure or a later arrival. The other grounds carry no clock: a different airport, more connection points, a downgrade, and changes specific to a passenger with a disability.

Source: 14 CFR 260.2 “Significantly delayed or changed flight” — ecfr.gov, checked 2026-09-15.

The time lines are hard edges: 2 hours 59 minutes of extra delay on a domestic flight is not a significant delay, while 3 hours 0 minutes is.

The departure ground runs in one direction only. A flight pulled 3 hours or more earlier qualifies by its departure time; a flight pushed later qualifies through its arrival time. A departure moved 3 hours later that still lands only 2 hours 40 minutes late, because the new schedule is shorter, meets neither time line.

The non-clock grounds read literally. A nonstop flight rescheduled with a stop on the way adds a connection point. An arrival moved to another airport in the same metro area still counts, because the ground names a different airport, not a different city.

The disability grounds apply only to a passenger with a disability. A disability-specific change to the connection or to the aircraft counts as a significant change even when both times stay inside the 3-hour or 6-hour lines. A downgrade to a lower class of service works the same way, with no time element at all. The 14 CFR 260.6(a) conditions still govern each ground: the refund follows only if you do not accept the changed flight.

Put the airline’s change notice next to your original confirmation, compare the departure and the arrival separately, and count the minutes before you answer the offer.

#How quickly must the airline pay the refund?

7 business days is the refund deadline in 14 CFR 260.2 for a credit card purchase. 20 calendar days applies to purchases made with cash, check, debit card or any other form of payment. A debit card sits in the 20-day group, not with credit cards. The rule calls meeting these deadlines a “prompt refund”.

Source: 14 CFR 260.2 “Prompt refund” — ecfr.gov, checked 2026-09-15.

The payment method, not the airline or the route, decides which clock runs.

These deadlines come from the final rule published on 26 Apr 2024 (89 FR 32760), effective 25 Jun 2024. Airlines had to comply with the fare, bag and ancillary refund provisions from 28 Oct 2024. Separately, the self-effectuating refund provisions of the FAA Reauthorization Act of 2024 took effect on 16 May 2024.

Source: Federal Register 2024-07177 and 2024-17602 — federalregister.gov, checked 2026-09-15.

Worked example: you paid $418 for a domestic ticket with a debit card, the airline cancels, and you reject the rebooking. The 20-calendar-day deadline applies, because 14 CFR 260.2 lists debit cards with cash and checks. Had you paid the same $418 with a credit card, the rule would require the refund within 7 business days instead.

Check your statement for the payment method you actually used, then name that deadline in your refund request.

#Can the airline give you a voucher or credit instead?

5 years is the minimum validity of a travel credit or voucher offered instead of a refund under 14 CFR 260.6(c) and 260.7. The airline may offer one only as an explicit alternative with notice of your right to a refund. You have to accept the credit affirmatively; until you do, the refund stays on the table.

Source: 14 CFR 260.6(c), 260.7 — ecfr.gov, checked 2026-09-15.

In April 2026 a passenger posting on r/unitedairlines wrote about a significantly changed booking: “At first, the system automatically gave me a travel credit, which I didn’t want.” They then asked for a full refund to their credit card and, by their account, got mixed answers. Check the voucher expiration date on any credit offered in place of a refund: less than 5 years falls short of the rule.

A “no change fee” fare is a different product. In a September 2025 r/frontierairlines thread, one passenger had read “no change/cancel fee” as refundable, and u/magiteck replied: “It means you don’t pay a fee to cancel, and instead retain 100% of what you paid as a travel credit.” That is a forum explanation of one airline’s fare, not a DOT rule. The 3 refund cases in 14 CFR 260.6(a) all start with the airline canceling or significantly changing the flight.

Dashboard vouchers are a third thing. On the DOT’s Airline Cancellation and Delay Dashboard (detail page last updated 11 Sep 2025), Alaska, Hawaiian, JetBlue and Southwest are marked Yes for a credit or voucher when a disruption within the airline’s control means a wait of 3 hours or more. Allegiant, American, Delta, Frontier and United are not marked Yes. All nine show No for cash compensation. These promises bind through each airline’s customer service plan, not as federal rights. The full table is on the airline customer service commitments page.

Before you take a credit instead of a refund, check each point:

• Your flight is canceled or meets a significant delay or change ground.
• You have not boarded or accepted the rebooked flight.
• The offer states your right to a refund and a validity of at least 5 years.
• You know your payment method: credit card (7 business days) or cash, check, debit card and other forms (20 calendar days).
• You have saved the change notice and your written reply.

An offer that leaves out your right to a refund or the 5-year validity falls short: decline it in writing and ask for the refund.

#Do you get bag fees and extras back?

12 hours is the domestic limit for a checked bag under 14 CFR 260.2: a bag not delivered within that time is significantly delayed, and with a Mishandled Baggage Report its fee is refunded. On international trips the limit is 15 hours if the US-foreign nonstop segment is 12 hours or less, and 30 hours if it is longer.

Source: 14 CFR 260.2 “Significantly delayed bag”, 260.5(b) — ecfr.gov, checked 2026-09-15.

Bag fee refunds: when a bag counts as significantly delayed

A nonstop segment of exactly 12 hours falls in the 15-hour row; one of 12 hours and 5 minutes moves to the 30-hour row.

The checked bag fee refund needs a Mishandled Baggage Report under 14 CFR 260.5(b); the hour limits alone are not enough. Airlines had to comply with the bag and ancillary refund provisions from 28 Oct 2024.

The refund returns the fee, not the value of what is inside. A US airline’s liability for the bag itself is a separate rule: on domestic flights with aircraft of more than 60 seats, 14 CFR 254.4 bars the airline from limiting it below $4,700 per passenger. The lost and delayed baggage page covers that route.

The ancillary fee refund follows the ticket. When a 14 CFR 260.6(a) refund is due, the full refund includes the ancillary fees you paid, not only the fare and taxes. A passenger bumped from an oversold flight has its own rule under 14 CFR Part 250: unused ancillary fees are refunded, separately from the denied boarding amounts on the bumped flight page.

File the Mishandled Baggage Report with the airline as soon as the bag fails to arrive, and keep your copy with the bag-fee receipt.

#What if your flight was only renumbered?

7 Jul 2027 is the end of DOT enforcement discretion for renumbered flights. Until then, the DOT does not enforce the cancellation-refund requirements of 14 CFR 260.6, 260.9 and 399.80(l) where a flight is merely renumbered, the passenger is rebooked on it, and there is no “significant change or delay”.

Source: Federal Register 2025-22140 and 2026-13675 (91 FR 41556) — federalregister.gov, checked 2026-09-15.

The flight number matters because 14 CFR 260.2 defines a canceled flight by it: a covered flight with a specific flight number published in the computer reservation system when the ticket was sold, but not operated. Read on its own, that definition could reach a flight that still leaves at the same time under a new number.

The DOT paused enforcement on 5 Dec 2025 and extended the pause to 7 Jul 2027. The requirement stays in the DOT flight refund rules. Only its enforcement is paused, and only for this case.

The discretion ends where a significant change begins. If the renumbered flight also arrives 3 hours or more later on a domestic trip, or 6 hours or more on an international one, or meets another significant change ground, the discretion no longer covers it. The refund conditions then apply as usual.

Worked example: your 8:05 departure keeps its route and time but gets a new flight number, and the airline moves your booking onto it. The DOT does not enforce the cancellation-refund requirements in that case. If the renumbered flight instead lands 3 hours 25 minutes after your original arrival time on a domestic trip, the significant-delay ground is met, and rejecting it keeps the refund.

Compare the renumbered flight’s times and connection points with your original booking before you accept the move, and cite 14 CFR 260.2 if a ground is met.

#What if the refund does not arrive?

30 days to acknowledge and 60 days to respond in writing are the airline’s deadlines for a complaint under 14 CFR 259.7(c). Write to the airline first, citing 14 CFR 260.6(a) and the deadline for your payment method. If the money still does not arrive, file a complaint with the DOT’s Office of Aviation Consumer Protection.

Source: 14 CFR 259.7(c); DOT File a Consumer Complaint — ecfr.gov, transportation.gov, checked 2026-09-15.

The DOT complaint form is online at secure.dot.gov/air-travel-complaint, which redirects to the Office of Aviation Consumer Protection form. By mail, write to the Office of Aviation Consumer Protection, U.S. DOT, 1200 New Jersey Ave SE, Washington DC 20590. The form page lists 855-368-4200.

The DOT directs the airline or ticket agent to respond to you, with a copy to the DOT. It does not investigate every service complaint, and relies on targeted and sample reviews instead; civil-rights complaints are the exception. The full process is on the DOT airline complaint page. Booked with American? The American Airlines refund page applies these rules to that airline.

Not your situation? A flight out of an EU or UK airport, or one covered by Canada’s Air Passenger Protection Regulations, has its own rules: see EU261, UK261 or Canada APPR. The which-law-covers-my-flight guide sorts mixed itineraries, and the transatlantic flight compensation guide covers EU261 and UK261 on flights between Europe and the US.

Send the airline a dated written request with your booking reference, the ground you rely on and your payment method, and keep the reply before you file with the DOT.

General information, not legal advice. For your specific case: the DOT Office of Aviation Consumer Protection or a consumer protection attorney.
