US DOT $The 24-hour rule: cancelling a flight you just booked

Checked 22 Sep 2026·8 min read

Booked a flight and changed your mind the same day? One of the US DOT passenger rules gives some bookings a 24-hour grace period, and it is narrower than most readers assume.

#US DOT $What does the 24-hour rule let you do?

24 hours is the window a covered airline must honor after you book: either hold your reservation at the quoted fare without paying, or let you cancel a paid booking for a full refund. DOT says airlines are not required to offer both; one or the other satisfies the rule.

Source: 14 CFR 259.5(a), (b)(4); DOT Refunds page — ecfr.gov; transportation.gov, checked 2026-09-22.

The rule is a term of the airline’s Customer Service Plan, which 259.5(a) requires every covered carrier to adopt and adhere to; DOT enforces it as a plan term. The plan must include holding a reservation at the quoted fare for at least 24 hours, or canceling one free for 24 hours, whichever the airline picks. So an airline offering a free 24-hour hold has already met the rule, and need not also refund a ticket you paid for at once. If the airline takes payment with the reservation, it must let you cancel the payment and reservation within 24 hours for a full refund.

Check the airline’s booking flow before you pay: a “hold without payment” option at checkout may already be the airline satisfying 259.5(b)(4), not an extra perk. How DOT holds airlines to the promises in their plans is set out on airline customer service commitments.

#Which bookings does the 24-hour rule cover?

7 days or more before departure, booked directly with the airline, on a flight to, from or within the United States operated by a covered carrier: all three conditions must hold for 14 CFR 259.5(b)(4) to cover your booking. Miss any one of them and the rule does not apply.

Source: 14 CFR 259.2, 259.3, 259.5(b)(4); DOT notice of 31 May 2013 — ecfr.gov; transportation.gov, checked 2026-09-22.

Timing: DOT confirms the requirement “applies to all reservations made seven days or more prior to the flight’s scheduled departure time.” Book six days out, and the rule does not apply, whatever the airline’s site implies at checkout. Carrier: a “covered carrier” is a US certificated or commuter carrier, or a foreign carrier on its flights to and from the US, where it operates at least one aircraft with 30 or more seats. Seller: DOT states the requirement “does not apply to tickets booked through online travel agencies, travel agents, or other third-party agents,” though an agent may choose to match it voluntarily.

Book directly on the airline’s own site or app if the protection matters to you, and check the departure date is at least a week out before you pay.

#How and how fast must the airline refund you?

24-hour cancellations must come with the offer of a full refund in your original form of payment, whether you ask by phone, in person or online. Online, DOT treats a cancellation page that does not offer that refund before you submit as a violation, and says a credit should not be pre-selected.

Source: DOT, Guidance on the 24-hour reservation requirement (31 May 2013); 14 CFR 260.2 — transportation.gov; ecfr.gov, checked 2026-09-22.

For a phone or in-person cancellation, DOT’s 2013 guidance requires the airline “to offer the requester a full refund in the original form of payment.” Online, it is treated as a violation not to offer that same refund “before the cancellation request is submitted”; a carrier credit may be offered alongside it, but it “should not be pre-selected as the default choice of refund form” or “appear as the more prominent refund option.”

Timing splits by payment method. For credit card purchases, refunds follow the timeframes in Regulation Z, 12 CFR Part 1026, and 14 CFR Part 374. Other payment methods get only “Department enforcement precedent,” no published day count. The 7-business-day and 20-day figures in 14 CFR 260.2 were written for a different trigger.

Look for the refund method shown before you click cancel, and pick the original form of payment if a credit is highlighted. If the airline offers no refund at all, file a complaint.

#What does the 24-hour rule not cover?

24-hour protection covers cancellation or a hold, not a free change. DOT states plainly that airlines “are not required to make changes to a ticket free of charge,” such as shifting the date or fixing a misspelled name, and on a fare priced as a round trip, the airline may refuse to cancel one leg alone.

Source: DOT Refunds page; DOT notice of 31 May 2013, footnote 3 — transportation.gov, checked 2026-09-22.

Keeping the booking but shifting the date is a different request, one the airline may charge for under its own fare rules. Round trips priced as a package face a second limit: DOT’s 2013 notice says that where a fare’s price is “conditioned upon the purchase of a roundtrip ticket, carriers may decline to honor the 24-hour reservation requirement unless the consumer agrees to cancel the entire itinerary.” Cancel only the outbound leg, and the airline can insist on the return leg too.

Read your fare rules before canceling one leg: DOT’s footnote reaches only a price conditioned on buying the round trip.

#What if you cancel after the 24 hours?

0 federal refund is owed if you cancel a non-refundable fare yourself after 24 hours and the flight still operates as scheduled. DOT states that a consumer who does this “is not entitled to a refund when the flight operates as scheduled.” The airline’s own cancellation or a significant schedule change is a different question.

Source: DOT Refunds page; 14 CFR 260.1(c), 260.2 — transportation.gov; ecfr.gov, checked 2026-09-22.

After the window closes, your own decision not to travel carries no federal refund right if the fare is non-refundable and the flight goes ahead as booked. The airline’s side is different: 14 CFR 260.2 defines triggers, the specific flight number sold to you not operating, or a significant delay or schedule change, that create an automatic refund regardless of fare type, if you reject the airline’s alternative or never respond and the flight leaves without you. Those triggers belong to the airline’s refund rules, a different page from the 24-hour rule covered here: that page does not reach a passenger who simply changes their own mind about a non-refundable fare.

If the airline disputes which trigger applies, contact the airline first, then file a DOT complaint online or by mail. DOT directs the airline to respond to you and does not investigate every service complaint itself.

#Is there a free cancellation window under UK or EU rules?

3 situations are all that UK261 and EU261 cover, under article 1(1): denied boarding, cancellation of the flight, and delay. Your own decision to cancel a booking is none of the three, so neither law gives you a free cancellation window the way the US 24-hour rule does.

Source: UK261 art. 1(1) — legislation.gov.uk; EU261 art. 1(1) — eur-lex.europa.eu, checked 2026-09-22.

Both regulations open with the same subject-matter article. UK261 and EU261 art. 1(1) state that the Regulation gives passengers minimum rights when they are “denied boarding against their will,” their flight “is cancelled,” or their flight “is delayed.” All three describe something that happens to your flight, not a choice you make. A passenger who books, then decides within minutes to cancel it themselves, fits none of the three, and no UK261 or EU261 provision creates a US-style 24-hour cooling-off period.

For a self-cancelled UK or EU booking, the fare’s own terms are the place to look. A refundable fare says so at booking; a non-refundable one may return nothing, whatever notice you give. This page does not cover other consumer law, so it names none. If the airline later cancels the flight itself, the refund rules are different: see the UK261 or EU261 refund-or-voucher page.

Read the fare conditions shown at the point of payment on a UK or EU booking. A free cancellation window there is a term the airline chose to add, not a right UK261 or EU261 gives you.

Not your situation? UK261 and EU261 cover departures from the UK and the EU, neither with a free-cancellation window for your own decision, per the section above. Canada’s APPR governs Canadian flights instead. Work out which law fits at which law covers my flight, or compare US and EU rules at transatlantic flight compensation.

General information, not legal advice. For your specific case: the US Department of Transportation or a consumer protection attorney.

#FAQ

Does the 24-hour rule apply to British Airways flights to New York?

14 CFR Part 259 reaches a foreign air carrier's flights to and from the US if it operates at least one aircraft with 30 or more seats, so a London to New York flight can be covered. The booking must still be made 7 or more days ahead, directly with the airline.

Can I cancel a Ryanair or easyJet flight for free within 24 hours?

No federal right covers that booking: 14 CFR 259.5(b)(4) is a US rule for flights to, from or within the United States. Neither UK261 nor EU261 gives a free-cancellation window for your own decision to cancel; both cover denied boarding, cancellation and delay only. Any free-cancellation term would come from the fare conditions.
