US major American Airlines and low-cost carrier JetBlue Airways have launched a reciprocal frequent-flyer pact and expanded on a previously-forged interline agreement.
The two carriers also say they continue to explore opportunities to expand commercial cooperation "where it makes sense to both airlines".
Under the new loyalty programme scheme, members of the American Airlines AAdvantage programme and JetBlue's TrueBlue programme can earn AAdvantage miles or TrueBlue points, respectively, in select markets beginning tomorrow.
Additionally, the interline agreement announced by the two carriers in March has been broadened to include one new American Airlines international market - New York JFK-Budapest, with service beginning in April - and nine new JetBlue domestic markets beginning 10 December.
The JetBlue markets are Boston to Baltimore; Charlotte, North Carolina; Newark; Orlando, Florida; Pittsburgh, Pennsylvania; Raleigh-Durham, North Carolina; San Francisco; Washington National; and Phoenix.
With today's announcement, customers will now be able to connect on flights to a total of 15 of American's international destinations departing from JFK and Boston Logan and 28 JetBlue domestic markets.
Customers are also now able to book American and JetBlue connecting itineraries on American's web site, representing a new option for booking interline service in the select markets connecting at JFK and Boston Logan.
