Flight Cancelled or Changed? US Airline Refund Rules and Deadlines in Plain Terms

By Smart Budget Sheets November 11, 2026
When US airlines owe a refund and how fast.

Waiting on an airline refund can wreck a tight month. In the US, Department of Transportation rules set out when you are owed cash back and how fast.

When you are owed a refund

Under the DOT refund rule that took effect in October 2024, you are entitled to a refund (not just a voucher) when:

  • the airline cancels the flight and you choose not to travel or rebook,
  • the flight is significantly changed: departure or arrival moved by 3+ hours domestic or 6+ hours international, a different airport, extra connections, or a downgrade in class,
  • checked bags are significantly delayed (bag fee refund), or a paid extra like wifi or seat selection is not provided.

How fast

  • Card purchases: within 7 business days.
  • Other payment methods: within 20 calendar days.

The refund should go back to the original payment method, in cash, unless you accept a voucher or credit. Read any “accept voucher” screen carefully before clicking.

If it is late

  1. Ask the airline in writing, citing the cancellation or change and the date.
  2. File a complaint with the US DOT (free, online). Airlines must respond.
  3. If you paid by credit card, a billing dispute with the card issuer for services not provided is another route. Check your issuer’s deadline, usually 60 days from the statement.

Budget buffer

Travel months are where refunds and reimbursements pile up. Track them as “money owed to me” in your budget and do not spend them until they land.

Rules can change; check the current DOT guidance for your case.
