US Department of Transportation rules require airlines to let you cancel a booking within 24 hours of purchase for a full refund to your original payment method, provided you booked at least seven days before departure. It applies to every fare including Basic Economy — this is the one window in which the cheapest ticket on the aircraft is fully refundable.
Key Travel Facts & Insights
The DOT requires airlines selling tickets for flights to, from or within the United States either to hold a reservation at the quoted fare for 24 hours without payment, or to allow cancellation within 24 hours of purchase for a full refund. Most carriers chose the second option.
The refund must go back to the original form of payment. An airline that offers only a voucher during the 24-hour window is not complying with the rule.
The rule only applies when the booking was made at least seven days before the flight departs. Book a ticket for tomorrow and the 24-hour window does not attach to it.
Some carriers apply the rule more generously than required. Alaska honours the 24-hour cancellation regardless of how far out you booked, and American offers a 24-hour hold in addition to the 24-hour refund. Others apply exactly the legal minimum.
The 24-hour window is genuinely useful as a planning tool, not just a safety net. If you find a good fare but need to confirm a hotel, a meeting date or a travelling companion, you can book, hold the fare, and cancel free within 24 hours if it falls through.
It is also the correct response to a booking mistake. Wrong date, wrong airport, misspelled name, wrong fare brand — cancel within 24 hours and rebook rather than paying a correction fee.
The rule applies to the ticket, but the practical process depends on who sold it. If you booked through an online travel agency or a consultant, cancel through them rather than with the airline directly — the airline may not be able to process a refund on a ticket it did not sell.
Some third-party sellers add their own service fee on top. The DOT rule covers the airfare; a separately disclosed agency service fee may not be refundable.
Yes. This is the one window in which Basic Economy is fully refundable. The rule applies to every fare class sold for travel to, from or within the US, including ultra-low-cost carriers like Spirit and Frontier, provided you booked at least seven days before departure.
It applies to any airline selling tickets for flights to or from the United States, including foreign carriers. Lufthansa, British Airways, Emirates and others all honour it on tickets sold in the US market.
The rule does not apply, and normal fare rules govern. Some carriers voluntarily extend the window anyway — Alaska is one — but you cannot rely on it. On a last-minute booking, check the fare rules before you pay.
