How can I change the date or time of a flight with American Airlines?

American date and time changes should be priced against the exact 13-digit ticket and all remaining coupons. Compare local dates, airports, connection length and any Basic Economy restriction before reissue. If American changed the schedule first, preserve that notification and assess the protected-change branch before paying for a voluntary modification. Use American Manage trips and locate both the record locator and the 13-digit ticket number. After action, verify the American ticket status, credit type and expiration, and all segments rather than relying only on the reservation display.

Important exceptions

  • A time change can also change the calendar date or airport after time-zone conversion.
  • Cancelling first can lose protected space, ticket value or later segments.
  • Do not confirm while any airport code, local date or operating carrier is ambiguous.
  • Stop if the replacement silently removes a segment or breaks the connection.
  • Do not assume seats, bags or upgrades automatically transfer to the new flight.

What to do next

  1. Open the controlled ticket

    Keep the record locator and 13-digit ticket number together.

  2. Compare the full journey

    Record both local dates, airports, connections, remaining coupons and operating carriers.

  3. Classify the trigger

    Separate a traveler-requested change from an American schedule change.

  4. Verify every coupon

    Inspect the reissued ticket status, credit type and all remaining segments.

Original worked example — fictional inputs

How can the calendar date move forward when the clock value gets smaller?

In this fictional example, both entries use the same departure airport's local calendar: Monday at 23:30 and Tuesday at 00:30. Tuesday is the later calendar date even though 00:30 is the smaller clock value.

What to do next

Write the date as well as the time in your change request. Compare the full revised itinerary, including your arrival deadline and every remaining flight.
