focused on New York JFK and Boston Logan airports, connecting the Irish carrier's transatlantic services with JetBlue flights to 29 North American destinations. Aer Lingus in 2008 became
JetBlue's first international partner when the carriers struck a cross-marketing pact. That deal enabled single tickets for itineraries including services from both, but initially was limited to the Aer Lingus website. Subject to government approvals, the new codeshare deal also would allow customers to book single tickets through travel agencies and provide one-stop check-in and baggage transfers. The code share is timed to start when Aer Lingus on April 3 transfers its JFK operations to JetBlue's Terminal 5 from Terminal 4.
