American Airlines (Dallas/Fort Worth) and jetBlue Airways (New York-JFK) tomorrow (July 20) will launch their partnership to offer customers convenient connections from New York and Boston.

American and jetBlue also announced today 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.

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, ME, Rochester, NY; or Richmond, VA.
