What determines whether and how I can change a flight?

First separate a voluntary change you request from a significant schedule change made by the airline. The U.S. twenty-four-hour reservation rule is not a general right to change a ticket without cost, while a qualifying airline schedule change can create a separate refund decision if you decline the changed trip and alternatives.

Need help with changing a flight?

Select your airline first. The phone option appears only when this offer covers the airline and request.

This offer does not cover that airline and request. Use the airline's official channels.

What this answer depends on

  • The airline may voluntarily permit a change.
  • The flight is scheduled to, from or within the United States.
  • The airline charged you directly for the relevant ticket or fee.
  • The listed time threshold includes the exact boundary value.
  • The change is made to a covered itinerary.
  • For a traveler with a disability, check whether the airport or aircraft change affects a required accessibility feature or a companion on the same itinerary.

Important exceptions

  • Do not apply this rule to a voluntary cancellation of an operating, unchanged flight.
  • A smaller time change can still qualify through a different listed trigger.
  • Do not infer that every flight-number, aircraft or seat change is significant.

Important unknowns

  • A voluntary change fee, fare difference, deadline and same-day option depend on separately verified ticket and airline conditions.
  • No free-change promise is made when the exact fare and seller terms are unavailable.

What to do next

  1. Identify who changed the trip

    Compare your original itinerary with the current itinerary before choosing an option.

  2. Check the booking channel

    Use the seller named on your booking record when reviewing the available change path.

  3. Review the exact ticket terms

    Check the fare conditions and any displayed price difference before confirming a change.
