FREQUENT FLYER GLOSSARY
What is the 24-hour cancellation rule?
The 24-hour cancellation rule is a consumer-protection window that lets a traveller undo a newly bought airline ticket, or hold it, for one day after booking. In the United States it is a Department of Transportation requirement: for a ticket purchased at least seven days before the flight's scheduled departure date and time, the airline must either allow the traveller to cancel and receive a full refund without a penalty for 24 hours, or allow the reservation to be held at the quoted price without payment for 24 hours. [1] Airlines are not required to offer both options, and the rule does not make later changes to the ticket free of charge. [1]

Key takeaways
- For a ticket bought at least seven days before the flight's scheduled departure date and time, the airline must either allow a cancellation with a full refund and no penalty inside 24 hours, or allow the reservation to sit on hold at the quoted price without payment for 24 hours. [1]
- The two options sit on different footing: an airline that accepts a reservation without payment must allow cancellation within 24 hours without a penalty, while an airline that demands payment at booking must allow the traveller to cancel the payment and the reservation within 24 hours and get a full refund. [1]
- Tickets booked through an online travel agency, a travel agent or another third-party agent are outside the requirement. [1]
- Bookings made less than seven days before departure do not carry the right, so a ticket bought inside 24 hours of departure is outside it. [1]
What does the 24-hour cancellation rule require?
A cooling-off rule of this kind attaches to the moment of purchase rather than the moment of travel: the traveller gets a short, fixed window after paying or reserving, during which the booking can be unwound without a penalty or kept in place at a locked-in price while other options are compared. The deadline runs from the booking, not from the departure date, and the length of the window does not stretch because the trip is far away.
In the United States the rule is set by the Department of Transportation for tickets purchased at least seven days before a flight's scheduled departure date and time. [1] The airline must provide one of two routes:
| Route | What the airline must allow | What the traveller ends up with |
|---|---|---|
| Cancel and refund | Cancellation of the reservation and a full refund, without a penalty, for 24 hours [1] | The fare returned; no ticket |
| Hold without payment | A reservation at the quoted price, with no payment, for 24 hours [1] | A held seat at a fixed price while the traveller decides |
Airlines are not obliged to offer both a hold and a refund option, so the traveller has to check the airline's policy before buying. [1] The duty follows what the airline does at the point of sale: an airline that accepts a reservation without payment must let the traveller cancel within 24 hours without a penalty, and an airline that requires payment with the reservation must let the traveller cancel both the payment and the reservation within 24 hours and receive a full refund. [1]
Why is a 24-hour hold not the same as a refund?
A hold and a refund solve different problems. A hold leaves the money in the traveller's account and freezes the quoted price, but it is not a purchased ticket; a refund route means the trip has been paid for and the fare comes back if the reservation is cancelled inside the window. [1] Because the airline picks which route to offer, a traveller who assumes a cash refund is waiting at the end of the 24 hours may find that only a hold was ever on the table. [1]
Department of Transportation consumer guidance describes the same split on the market side: many large airlines will hold a reservation for around 24 hours without payment, while others require payment when the reservation is made and then provide a full refund if the traveller cancels in the first day or so. [4]
Neither route is a free change. Airlines are not required to make changes to a ticket free of charge — for example, moving the booking to a different date or correcting a misspelled name on the reservation. [1] Where a change fee plus any difference between the original fare and the current fare would cost more than starting again, requesting a refund and rebooking can be the cheaper path, though fares move quickly. [1] Changing a ticket that has already been issued is a separate process, covered under reissue and revalidation and in the award ticket change checklist for redemptions.
Letting a booking lapse is not the same as cancelling it either. Travellers holding confirmed reservations they do not intend to use are advised to notify the airline, because otherwise the carrier may cancel onward or return reservations on the trip. [4] The same exposure sits behind the no-show fee term.
Does the rule cover tickets booked through a travel agent?
No. The 24-hour refund and reservation requirement does not apply to tickets booked through online travel agencies, travel agents or other third-party agents. [1] Those agents are free to apply the same or similar procedures as a service to customers, but the requirement itself does not reach them. [1] A traveller who booked through an agent should contact the agent directly to obtain a refund before approaching the airline. [1]
Responsibility for the money follows the merchant of record — the entity named on the card or bank statement for the purchase. [1] Ticket agents that are the merchant of record are required to make proper refunds of airfare when a flight to, from or within the United States is cancelled or significantly changed by an airline. [1] That obligation concerns cancellations and significant changes made by the carrier, which the US flight cancellation and refund guide walks through, and it is distinct from the 24-hour window described here.
What does the rule not cover?
- Bookings made close to departure. The requirement is written for tickets purchased at least seven days before a flight's scheduled departure date and time. [1] A booking made closer in than that, including any booking made inside 24 hours of departure, falls outside it. [1]
- Free changes. The right to cancel or hold is not a right to move the trip: airlines are not required to make changes to a ticket free of charge under this rule. [1]
- Third-party bookings. Tickets bought through an online travel agency, travel agent or other third-party agent are excluded, although the agent may choose to offer something similar. [1]
- Geography. Department of Transportation refund guidance is framed around flights to, from or within the United States, and that framing carries into how it describes ticket agents' refund duties. [1] This entry describes the United States rule only; it does not establish a worldwide right to cancel a ticket within 24 hours of booking, and cooling-off rules in other markets are not covered here.
- Airline-specific policy. Whether a given carrier offers a hold or a refund, and what it charges once the window has closed, is set by that carrier, so the policy has to be read before the ticket is bought. [1]
Frequently asked questions
Can I cancel any flight within 24 hours of booking?
Only if the ticket was purchased at least seven days before the flight's scheduled departure date and time. [1] Inside that seven-day run-in the requirement does not apply. [1]
Do I get a refund or just a hold?
It depends on the airline, which is not required to offer both a hold and a refund option. [1] Check the carrier's policy before purchasing. [1]
Does the rule apply to tickets bought on an online travel agency?
No. The 24-hour refund and reservation requirement for airlines excludes tickets booked through online travel agencies, travel agents and other third-party agents. [1]
Can I use the 24 hours to change my travel dates instead?
Not free of charge. Airlines are not required to make changes to a ticket free of charge, such as moving to a different date or correcting a misspelled name on the reservation. [1]
What can I do if the airline refuses?
Give the airline a chance to resolve the problem first. [6] Carriers that fly to, from or within the United States must state on their websites how and where complaints can be submitted. [6]
