Last-minute changes or accidents can happen unexpectedly. American Air-lines Changes Flight Policy. If you need to modify your flight, and you are looking for a method to do it, this adjustment has been made to make things easier.
• American Airlines' Change Fees are not applicable to short-haul and long-haul domestic flights. They have also been eliminated for prima-ry cabin and premium cabin tickets.
• You would also be eligible for standby on domestic flights that were pre-viously scheduled. This includes flights from Puerto Rico to the same destination in the US Virgin Islands on the same day.
• You can now purchase upgrades, seats and priority boarding if you have basic economy.
• You can cancel your trip online, and rebook after you have all the neces-sary information including basic economy costs.
