American Airlines and JetBlue’s Northeast Alliance is taking off, with new international services, extra domestic flights and hundreds of codeshare routes taking wing this northern fall and winter.

The carriers say they are “providing customers the most choice in the Northeast, on the best product, and with a premium experience”, as travellers return to the sky.

As part of their Northeast Alliance, JetBlue and American will operate more than 700 daily flights from New York and Boston this winter, something the carriers say will give customers more choice than any other airline.

The alliance will also see the carriers operate the largest international network from New York with service to 47 international destinations, plus offer lie-flat seats on all transcontinental routes in 2022.

Starting this northern fall, AAdvantage Elite and TrueBlue Mosaic members will also enjoy the first phase of reciprocal benefits.

“Our Northeast Alliance with JetBlue gives customers more choices and benefits and raises the bar on offering an industry-leading experience,” said American’s Chief Revenue Officer, Vasu Raja.

“With JetBlue’s domestic strength and American’s growing international network, we are unlocking more destinations for travelers, more flying for both our teams, a better suite of products and a premium experience in the Northeast.”

JetBlue — New York’s ‘Hometown Airline’ and leading low-fare carrier, and the largest airline in Boston – also announced that customers can purchase tickets for several new markets launching this northern fall, including four new destinations the airline is adding to its route map.

“With demand for travel returning, JetBlue’s new low fare flying — along with the broader growth made possible with American through the benefits of the NEA — is well-timed for us to best meet the needs of more travellers in the Northeast and introduce more competition with new flying,” said JetBlue’s Northeast Alliance vice president, Dave Fintzen.

“Whether it’s new cities, more lie-flat service on cross country routes, enhancing our combined schedules on key routes, or expanding benefits for corporate customers as they return to the skies, the North East Alliance is going to make it as easy as possible for travellers in the Northeast to come back to flying.”

American Airlines and JetBlue say as result of the partnership, so far this year customers have gained access to 57 new markets and more than 110 codeshare routes from Boston and New York, connecting the Northeast to almost 150 worldwide destinations, including 10 new international routes American previously announced.

These routes, made possible by the Northeast Alliance, include new service from New York John F. Kennedy International Airport (JFK) to Tel Aviv, Israel (TLV), which launched in May; JFK service to Athens, Greece (ATH), which launched in June and JFK service to Delhi, India (DEL), which will launch October 31, 2021.
