American Airlines, JetBlue launch codeshare partnership, add 33 new routes

American Airlines and JetBlue’s partnership has taken off. 

On Thursday, the two airlines launched their "Northeast Alliance," a codeshare partnership that brought together almost 80 flights from both carriers -- including 33 brand-new routes. All routes are either into or out of Boston or New York City’s three airports.

Now customers can book 49 codeshare routes operated by JetBlue using the American Airlines website, or 25 codeshare routes operated by American Airlines using the JetBlue website, according to the launch announcement.

Though they can be booked now, the codeshare flights won’t begin flying until Feb. 25.

In its announcement, American Airlines said codesharing "provides access to a broader network by allowing travelers to book a single itinerary directly with their preferred airline for flights operated by a partner airline."

The airline also said that more markets in the Northeast would be added to the partnership "regularly throughout the first half of this year."

"In the months ahead, we’ll continue to create a seamless experience that’s easy for our customers, supports our communities and leads to more growth for our team."
