Mileage Multiplier

Multiply your miles on every flight

Reach your travel awards faster by purchasing AAdvantage® bonus miles with Mileage Multiplier. Buy miles each time you fly an eligible trip on American and American Eagle® and be on your way to your next award!

Here's how it works

Make your reservation and include your AAdvantage® number. To multiply your miles you can either:

  • Select Mileage Multiplier when booking a flight on
  • Check in for your flight on
  • Check in for your flight using an airport self-service machine

Then, simply use your credit card to purchase Mileage Multiplier for yourself or anyone you're traveling with. You'll see how easy it is to increase your miles for that next trip.

American customer service

Already checked in?

Even if you have already checked in for your flight, you can still multiply miles for your trip:

  • Stop by an airport self-service machine and select the option to reprint boarding pass or check bags
  • Visit My Reservations on and select Mileage Multiplier up to 45 minutes before flight departure

In most cases, the AAdvantage® miles you purchased will post before you arrive at your destination.

When you add Mileage Multiplier to the many ways to earn AAdvantage® miles, you’ll find your miles will grow even faster!
