Your cancellation window depends on when you booked and which airline you're flying

Most airlines let you cancel a flight up until the moment it departs, but the refund you receive depends on the ticket type and how far in advance you cancel. Basic economy tickets often cannot be refunded at all—you get a credit toward a future flight instead. Standard tickets usually become non-refundable 24 hours after purchase. First-class and premium cabin tickets typically stay refundable longer. The key is checking your specific airline's policy before you book, because the rules vary widely.

If you booked through a third-party site like Kayak, Expedia, or Google Flights rather than directly with the airline, you may have an extra cancellation window with that site—but the airline's own rules still explore once you're in their system. Some third-party sites offer their own refund protection for a fee, which is separate from what the airline offers.

Key Takeaways

  • You can cancel most flights right up until departure, but refund may be able to access ends much earlier—usually 24 hours after purchase for standard tickets.
  • Basic economy fares almost never refund; you receive a credit toward future travel instead, which may expire after one year.
  • If you cancel within 24 hours of booking, federal rules require airlines to refund your full fare regardless of ticket type.
  • Cancellations made close to departure may still process, but you will forfeit the ticket value unless you have a refundable fare.

The 24-hour federal rule that applies to all airlines

The U.S. Department of Transportation requires all airlines to refund your full fare if you cancel within 24 hours of booking, no matter what type of ticket you bought. This applies whether you booked directly with the airline or through a third party. The 24 hours starts from the moment your booking confirmation is issued, not from when you complete payment.

To use this rule, you must cancel through the airline's website, phone line, or ticket counter—not through a third-party site. If you booked on Expedia or Kayak, go to the airline's own cancellation page and reference your confirmation number. The refund must be issued to your original payment method within seven business days, though most airlines process it faster.

Refundable versus non-refundable tickets and what happens at each stage

Refundable tickets return your full fare if you cancel at any point before departure. These are typically first-class, business-class, or premium economy fares. Some airlines also sell refundable economy tickets at a higher price. If you hold a refundable ticket and cancel one hour before takeoff, you get your money back.

Non-refundable tickets (the standard economy option on most airlines) become locked in after 24 hours from purchase. Once that window closes, you cannot get cash back. You receive a credit toward a future flight on the same airline instead. That credit usually stays valid for one year from your original booking date, though some airlines have extended or shortened this during specific periods. If you do not use the credit within the validity window, you lose it entirely.

Basic economy fares are the cheapest option and are always non-refundable. You cannot even convert them to a credit—the airline keeps the money. Your only option is to rebook on a different flight at no additional cost if seats are available, but you cannot get the original purchase price back.

What happens if you cancel close to departure

You can cancel a flight minutes before it departs, but the refund outcome does not change. If your ticket is non-refundable and you cancel one hour before takeoff, you still receive only a credit, not a refund. The airline does not penalize you for canceling late—the refund rules are the same whether you cancel two weeks early or two minutes early.

The practical difference is that rebooking becomes harder. If you cancel a week in advance, the airline has many open seats on other flights. If you cancel an hour before departure, most flights that day are full, and you may have to wait days for an available seat. Your credit remains valid, but using it may require paying a change fee or accepting a flight at an inconvenient time.

Canceling through third-party booking sites versus the airline directly

If you booked through Expedia, Kayak, Google Flights, or another third-party site, you have two cancellation options: cancel through that site or cancel directly with the airline. Canceling through the third-party site is often slower because they must process your request and then contact the airline. Canceling directly with the airline is faster and gives you when ready confirmation.

To cancel directly with the airline, visit their website, call their phone line, or go to the airport ticket counter. You will need your confirmation number, which appears in your booking email. The airline will process the cancellation in their system and issue the refund or credit according to their policy, regardless of where you booked. Some third-party sites charge their own cancellation fees on top of the airline's policy, so read the fine print before booking.

How to find your airline's specific cancellation policy before you book

Each airline publishes its cancellation rules on its website, usually under a section called "Manage My Booking," "Cancellation Policy," or "Fare Rules." Before you complete a purchase, click the fare details or "what's included" section—most booking pages show whether the ticket is refundable or non-refundable right there. If the page says "non-refundable" or "credit only," that is your answer.

If you are comparing prices across airlines, check the cancellation policy for each one. A ticket that is $50 cheaper but non-refundable may cost you more in the long run if your plans change. Airlines also offer optional cancellation protection or travel insurance at checkout—read what it covers, because some policies only reimburse if you cancel for specific reasons (illness, death in the family) rather than any reason.

What to do if you need to cancel but miss the refund window

If your ticket is non-refundable and you have passed the 24-hour purchase window, you cannot get a refund. You receive a credit instead. That credit is yours to use on any future flight with that airline, on any date, to any destination they serve. You do not lose it when ready—it stays valid for one year (or whatever period that airline sets).

If you cannot use the credit before it expires, some airlines allow you to transfer it to another person or donate it. Check your airline's policy on their website. A few airlines have sold credit transfer services during specific periods, though this is not standard. If the credit expires unused, the airline keeps the money.

Frequently Asked Questions

Can I cancel a flight the day before it leaves and still get a refund?

Only if you have a refundable ticket. Non-refundable tickets become locked in after 24 hours from purchase, so canceling the day before departure gives you a credit, not a refund. The 24-hour refund window is measured from when you booked, not from when you fly.

What if I cancel within 24 hours of booking but after the airline's website says my ticket is non-refundable?

Federal law overrides the airline's non-refundable label. You are may have access to to a full refund if you cancel within 24 hours of purchase, regardless of ticket type. Contact the airline directly with your confirmation number and cite the Department of Transportation rule if they resist.

Do I lose my credit if I don't use it within a year?

Yes, in most cases. Credits expire one year from the original booking date (though some airlines have changed this temporarily). After that date, the credit is gone and the airline keeps the money. Check your airline's policy on their website to confirm the exact expiration date for your credit.

If I booked through a third-party site, do I cancel there or with the airline?

You can do either, but canceling directly with the airline is faster. Go to the airline's website with your confirmation number. The airline will process the cancellation according to their policy. Canceling through the third-party site may take longer because they have to relay your request to the airline.

Can I cancel a basic economy ticket and get a credit?

No. Basic economy fares are non-refundable and non-changeable on most airlines. You cannot convert them to a credit. Your only option is to rebook on a different flight at no additional cost if the airline has availability, but you cannot recover the purchase price.
