Mastercard has a new promotion offering a $50 discount on an American Airlines flight if you make a booking on the AA.com website by September 30, 2021. You’ll receive a code for $50 off your next trip.
If you have a Mastercard, there’s no reason not to register in case you wind up booking an American Airlines flight by September 30. You don’t even have to enter the Mastercard’s details in order to register.
