If imitation is the sincerest form of flattery, British Airways should be pleased. You’ll recall from our last issue that BA is going after your transatlantic dollar by offering North American members the chance to earn at least 50,000 miles for every transatlantic roundtrip flown in ClubWorld or FIRST.

Not to be outdone, both American AAdvantage and Continental OnePass have now matched the offer. AAdvantage members traveling in business and first class on U.S.-London flights through Apr. 30 will earn a 42,000-mile bonus; OnePass members in BusinessFirst will earn the same.

US Airways, while not quite matching the offer, is offering its own bonus for trips between the U.S. and London/Gatwick or Manchester. Through March 1, Dividend Miles members on that route will earn 7,500 bonus miles in coach and 15,000 bonus miles in Envoy Class.
