American Airlines and JetBlue Airways implement their commercial agreement on routes into and out of New York JFK and Boston. American and JetBlue also announced that they have agreed to begin a frequent flyer relationship later this year. Members of American’s AAdvantage program and JetBlue’s TrueBlue customer loyalty program will be able to earn AAdvantage miles or TrueBlue points, respectively, when they fly only on the cooperative interline routes listed below.

These announcements are the next steps toward enhancing the cooperation between American and JetBlue since the two airlines announced their new partnership in March.

Customers will be able to book convenient, interline service in non-overlapping markets from New York’s John F. Kennedy International Airport (JFK) and Boston’s Logan Airport (BOS) through travel agencies, most major North American online travel agency websites, American Airlines ticket counters, or by calling American Airlines Reservations at 800-433-7300.

Both American and JetBlue are also working to make flights offered through the agreement available for sale on each other’s websites.

Under the cooperative agreement, customers will be able to easily connect between 14 of American’s international destinations departing from JFK and Boston, including Barcelona, Spain; Rio de Janeiro, Brazil; and Tokyo and 18 JetBlue domestic markets, including Portland, Maine; Rochester, N.Y.; or Richmond, Va. None of the routes on which the airlines will cooperate overlap current flights flown by the other. A full list of the cities for each airline is available at the end of this release.

Customers of both airlines will benefit from improved connections, while each airline will see additional customers fed into their networks – JetBlue’s domestic network and American’s international network to Europe, Asia, and South America.

“This new agreement with JetBlue complements both airlines’ networks and greatly benefits our respective customers,” said Gerard Arpey, Chairman and CEO of American Airlines. “It will also provide important opportunities for us to grow American’s international traffic into and out of New York and Boston.”

“We are pleased to extend our route network, offering customers well-timed international connections on American and introducing new customers to the award-winning JetBlue Experience,” said Dave Barger, CEO of JetBlue. “As the largest domestic carrier at JFK and Boston, and with our new home at Terminal 5 at JFK, we are in a natural position to take advantage of these important partnership opportunities.”

As announced previously, on Nov. 1, American will transfer eight slot pairs at Ronald Reagan National Airport and one slot pair at White Plains, N.Y., to JetBlue, while JetBlue will transfer 12 slot pairs at JFK to American.
