Joanna Geraghty, the CEO of the airline who was recently appointed, is Irish-American. "JetBlue's entrance into Dublin is set to introduce a new era of low fares and great service between Ireland and the Northeast," she said.

Between now and September 30, JetBlue will operate Airbus A321neo aircraft on the Irish routes.

There will be two types of onboard seating available: the Core, an economy cabin with 144 seats, and Mint, a luxury business class experience featuring 16 lie flat suites.

With free wifi, increased legroom, and creative meal options, the airline says that new Core cabin offers an upgraded level of service.

The move is probably going to make the transatlantic routes from Ireland, which are now flown by Aer Lingus and several other airlines, more competitive.

The operator of Dublin Airport, daa, is requesting that the airport's passenger cap be raised from the current 32 million to 40 million as it approaches capacity at the same time as the new routes are launched.

According to Dublin Airport Managing Director Gary McLean, "JetBlue's arrival is very good news for both passengers and Ireland, and these new direct routes between Dublin and New York and Boston are going to prove really popular."

"Demand for transatlantic travel has never been higher, with stronger than ever business links continuing to grow between Ireland and the US."

"These new services from JetBlue will mean greater choice and value for our passengers and Dublin Airport looks forward to working with JetBlue to ensure they are a flying success."

The route's arrival will be viewed as a significant step forward for the local tourism sector, since Americans account for 20% of all foreign visitors to Ireland each year.

"As an island destination, we know there’s a proven correlation between direct, convenient access and growth in inbound tourism, so these new flights will certainly help boost visitor numbers and the overall economic value of tourism from the United States in 2024 and beyond," Alice Mansergh, Tourism Ireland's deputy chief executive.

"Tourism Ireland is committed to working with JetBlue, Dublin Airport and our other key partners, to drive demand for these transatlantic flights, and all other services to Ireland, to help maintain our vital network of routes and services."

However, the opening of further transatlantic lines will raise concerns about the rise in airline emissions at a time when they ought to be declining once more.

According to JetBlue, it has set science-based goals to reduce aircraft emissions by 50% per seat from 2019 levels by 2035.

By 2040, it hopes to achieve net zero carbon emissions, ten years ahead of industry objectives.

Presently, the airline procures sustainable aviation fuel from three US suppliers and collaborates with other companies regarding fuel investment.
