The latest development in JetBlue’s quest for European domination is the announcement of the expansion of its codeshare partnership with Irish flag carrier Aer Lingus.

“More than 13 years after Aer Lingus because our very first international airline partner our relationship continues to strengthen in ways that bring more benefits to customers on both sides of the Atlantic,” said Joanna Geraghty, President and Chief Operating Officer at JetBlue.

The expansion of the codeshare agreement between the 2 airlines means that more routes will share flight numbers and all the benefits that come with it.

Let’s review what you need to know.

JetBlue and Aer Lingus’ Codeshare Expansion

JetBlue flight numbers will now appear on the following 4 Aer Lingus-operated routes between the Northeast U.S. and Ireland:

Dublin (DUB) to Boston (BOS)
Dublin (DUB) to New York (JFK)
Shannon (SNN) to Boston (BOS)
Shannon (SNN) to New York (JFK)

According to the airline, this is just the beginning, with more Aer Lingus routes between the U.S. and Ireland, the U.K., and beyond also set to welcome JetBlue’s B6 flight number. The new codeshare routes are in addition to the existing 30+ JetBlue routes that also carry Aer Lingus’ EI flight numbers.

“All at Aer Lingus are looking forward to extending a warm Irish welcome to more JetBlue customers,” said Lynne Embleton, CEO of Aer Lingus.

The aircraft used on the routes are a mixture of brand-new Airbus A321neoLRs and older Airbus A330s. Both feature lie-flat seats in their respective business class cabins.

What This Means for You

This codeshare relationship allows you to book a single-ticket itinerary from JetBlue-served cities across the U.S. to Ireland via a connection onto an Aer Lingus flight at either New York’s Kennedy or Boston’s Logan airports.

“Customers can now travel seamlessly to Dublin and Shannon airports as we continue to connect friends and families, businesses and colleagues from the U.S. and Europe,” said Embleton.

Booking a codeshare flight also means that your bags will be checked through to your final destination and you’ll be protected should 1 of your flights experience a delay or cancellation that leads to a missed connection.

Upon returning to the U.S., passengers will be able to clear U.S. customs in Dublin and Shannon thanks to both airports being home to U.S. Customs and Border Protection (CBP) Preclearance facilities, which guarantees an easy and seamless arrival into the U.S.

Final Thoughts

JetBlue continues to expand its reach across the Atlantic into Europe.

Now, JetBlue loyalists have the possibility of reaching the wonders and beauty of the Emerald Isle with JetBlue codeshare flights rather than having to go with a competitor.

After an exciting 2021 — with its highly anticipated arrival into London and now an expansion of its codeshare relationship with Aer Lingus — we’re excited to see what 2022 will hold for JetBlue.
