You can pay for up to 3 checked bags at check-in on the company's website or in-app (from 24 hours before departure until 4 hours before departure).

RIf you need to check more than 3 pieces of luggage, you can add more luggage at the airport according to the luggage allowance.
Simply earn or redeem miles with American Airlines or AAdvantage partners every 24 months. US Airways will automatically extend your mileage expiry date by 24 months from your most recent qualifying activity date. Your e-wallet will display your existing Miles and their earliest expiry date. If you are under 21, you are not subject to the 24-month qualifying activity period. After turning 21, you must be bound by a 24-month activity period and must have mileage earning or redemption activities within 24 months of turning 21 in order to retain miles.
You can use the flight discount to book American Airlines and affiliated flights (flights with "AA" in the flight number) departing from the United States, the USA Virgin Islands and Puerto Rico. US Airways does not believe the discount is valid for travel on other airlines, surcharges, or other American Airlines products or services.
A same-day flight change will allow you to confirm a seat on a different flight on the day of departure, on any American Airlines and/or American Eagle flight for which a suitable seat is available. US Airways believes that the replacement flight must have the same departure and destination, and your flight change can only be confirmed within 24 hours before the departure of the flight you want to change.
