When American Airlines and JetBlue announced their interline agreement at the end of March 2010, the new partnership didn’t include reciprocal frequent flyer benefits and there was speculation about whether members would eventually be able to earn miles on either airline. The answer is yes. The two carriers have announced that they will be expanding their relationship and launching a reciprocal frequent flyer agreement. American AAdvantage and JetBlue TrueBlue members can choose to earn AAdvantage miles or TrueBlue points in select markets. The commercial agreement has also been broadened to include one new American Airlines international market and nine new JetBlue routes. Members can earn miles or points on any itinerary that includes eligible flights, whether or not those flights are used in conjunction with any other connecting flights. JetBlue members can now earn points on American Airlines flights between Boston and London Heathrow or Paris and between New York JFK and 15 international destinations. American AAdvantage members can earn miles on JetBlue flights between Boston and 17 domestic destinations and between New York JFK and 18 domestic destinations.
