Go to your reservations and select the ticket you want to change.

Customers must pay a lower fee if they modify their reservations the same day as their ticket purchasing, per United Change Flight policy.

Updated ticket information will be sent to your registered email address.

Regardless of the fare category, American Airlines offers its passengers free, limited itinerary modifications within 24 hours of booking.

You may cancel your airline ticket at any moment before the scheduled departure if it is allowed under the policy. You will receive a complete refund from the original method of payment after cancelling.

However, if you are a member of the military or a government employee on duty, the airline will not charge you for any cancellation fees.

The tickets are not refundable and cannot be transferred after 24 hours.

If you wish to delete a single ticket from a group reservation or a single-leg ticket, which is the return from a round trip, you cannot do it online because this is only allowed for one passenger.
