The 24 hour rule does not reach your booking site

Does the 24 hour cancellation rule apply to Expedia bookings?

No. The Department of Transportation answers it in one line on its refunds page, read on 17 September 2026 and carrying a last updated date of Friday, 7 November 2025. The 24 hour refund or reservation requirement for airlines does not apply to tickets booked through online travel agencies, travel agents, or other third party agents. Same seat, same flight, same fare, bought through a booking site, and the federal protection you were counting on is not there.

The requirement is narrow even where it does apply. For airline tickets purchased at least seven days before the flight's scheduled departure date and time, the airline must do one of two things. Either let you cancel the reservation and receive a full refund without a penalty for 24 hours, or let you reserve the ticket at the quoted price without paying for 24 hours. Buy six days out and neither option is owed to you.

That is the whole answer. What follows is why a federal rule stops at the booking site, what an airline is allowed to hand you instead of your money back, and which refund rights do survive a third party booking.

Why does a federal rule stop at the booking site?

Because it was never written as a passenger right. It sits inside the customer service plan that covered airlines have to adopt, at 14 CFR 259.5(b)(4), which requires reservations to be held at the quoted fare without payment, or cancelled without penalty, for at least twenty-four hours after the reservation is made, if the reservation is made one week or more before the flight's departure. It is an obligation on the carrier's own sales conduct, nothing more.

Part 259 is explicit about who it binds. The applicability section covers all the flights of a US certificated or commuter air carrier running scheduled passenger or public charter service with any aircraft originally designed for 30 or more seats, and all flights to and from the United States of a foreign air carrier doing the same. A ticket agent operates no aircraft and holds no carrier certificate, so nothing in part 259 reaches one.

Expedia, Priceline, Booking.com and the rest are ticket agents in the Department's vocabulary, the same category as the travel agent on the high street. Where the agent is the merchant of record, your money never touches the airline at the point of sale, and the cancellation window is whatever that agent chose to publish in its own terms. It can be 24 hours, it can be zero, and it can differ by fare on the same results page.

Can the airline give me a hold instead of my money back?

Yes, and this is the part almost nobody carries. The DOT page states that airlines are not required to offer both a hold and a refund option. Either one satisfies the requirement in full.

So an airline that publishes a free 24 hour courtesy hold, where you lock the quoted fare without paying, has already complied. If you skip the hold and pay for a nonrefundable ticket on that same airline's own website, there is no federal 24 hour cancellation window waiting behind it. The hold was the protection. Paying straight away is how you decline it. Our note on American's free 24 hour hold shows what that looks like in practice.

Two more limits sit in the same DOT answer. Where an airline accepts a reservation without payment it must let you cancel inside 24 hours without penalty, and where it requires payment with the reservation it must let you cancel the payment and reservation inside 24 hours and take a full refund. But the rule buys a cancellation, never a free amendment. DOT says plainly that airlines are not required to make changes to a ticket free of charge, so a wrong date or a misspelled name is still a change fee, and refunding and rebooking is sometimes the cheaper move.

What am I still owed if I booked through an OTA?

Plenty, just not a cooling off period. The refund rights that actually matter survive a third party booking. DOT states that ticket agents, meaning travel agents and online travel agencies, 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. That is the big one, and it does not depend on who sold you the ticket.

Merchant of record is the entity shown on your card statement for the ticket purchase. Find that name before you start chasing anybody, because it decides who owes you. The plumbing behind it is federal too. Under 14 CFR 260.6, once you ask the agent for a refund, the carrier that cancelled or significantly delayed or changed the flight has to tell the agent without delay whether you are eligible, and where the agent does not hold your money the carrier has to transfer the funds to it promptly. The agent's own deadline is covered in who owes you the refund when an agency booked it.

One carve out is worth memorising. Ancillary fees do not follow the same route. DOT says ticket agents are not responsible for refunding optional service fees, or baggage fees when a checked bag is significantly delayed or lost, and that you must request those from the airline even where the agent was the merchant of record for them. Seat selection, wifi, bags, lounge access, all of that goes to the carrier.

How do I cancel a flight within 24 hours of booking?

Order matters here, and the right order is the opposite of what most people try.

• Find the merchant of record on your card statement or confirmation email. That name, not the airline logo on the itinerary, decides who you talk to.
• If a booking site took the money, contact the booking site first. DOT says to contact the travel agent directly to obtain a refund before contacting the airline.
• Read the cancellation terms on the itinerary while the 24 hours are still running, and screenshot them with the date visible. A voluntary policy can be withdrawn at any time, a dated screenshot cannot.
• If you bought direct and paid, ask for the 24 hour refund and state that the ticket was purchased at least seven days before scheduled departure. That sentence is the whole test.
• If you bought direct from an airline that publishes only a hold, stop expecting a refund and price the change fee plus the fare difference instead.
• Keep the timestamp of the original booking. The window runs from when the reservation was made, not from when you spotted the mistake.

Does the same 24 hour window exist outside the United States?

Not as a flight rule. The US requirement travels with the carrier, not with you. It reaches every flight of a US certificated or commuter carrier wherever it operates, and the flights a foreign carrier runs to and from the United States. A European airline flying between two European cities is outside part 259 altogether, so nothing federal obliges it to offer you a hold or a 24 hour refund.

European passengers get a different and in some ways stronger set of rights, and they are triggered by what the airline does to the flight rather than by a change of heart. Cancellation, long delay and denied boarding carry fixed cash amounts, and the mechanics are in our EU261 flight compensation guide. There is no equivalent cooling off period for a seat you simply no longer want.

Packages run on a third track again. Where the flight sits inside a package holiday, the refund deadlines belong to package rules rather than to any airline customer service plan, which is the subject of package holiday refunds in 14 days. Where the money at risk is the hotel, the transfer and the deposits rather than the seat, what travel insurance actually covers is the more useful read.
