When you book a flight using cash or True Blue points, there are two possibilities. You must log into the official AAdvantage account or input the name and six-digit record locator on the official website if you make a cash reservation.
If you used your TrueBlue points to book this flight, things could become complex. Most of the time, changing award flights online & speaking to an American Airlines live person is not possible.
Additionally, there are no additional fees associated with reserving award flights, including no change fees. However, you could have to pay for the additional miles owed for your upcoming travel.
