Flying to Europe between now and July 31? Good. Flying on a first-, business-, or full coach-fare ticket? Even better. Because, bonus miles.

Offer Details

Through July 31, AAdvantage members can earn up to 50,000 bonus miles when traveling roundtrip between the U.S. and Europe on American, British Airways, Finnair, or Iberia, as follows:

• 2,000 bonus miles for select discounted coach fares

• 25,000 bonus miles for first- or business-class fares

The bonus may be earned twice, for two roundtrips.

Deal or No Deal

The bonuses range from hefty, for more expensive tickets, to paltry, for discounted coach. And those flying on discounted coach—by far the most popular fare type—will have to be mindful of the qualifying fare codes within that rather broad category. On American flights, for instance, the eligible discounted coach fare types are H, K, M, L, W, V, G, Q, N, and O.

Your mileage, in other words, may vary.
