You will know by now that JetBlue has added two more European routes. Next April, it’ll take off from Boston to Barcelona, followed by Boston to Milan in May. The latter is the troubled carrier’s new longest service. When other carriers are included, they were two of 13 new long-haul routes announced in just two days.

JetBlue’s European foray began amid the pandemic in 2021. In 2026, the airline currently plans a record 14 European routes, all of which are from its top two US airports: New York JFK and Boston. It will serve nine airports on the other side of the Atlantic for the first time. It plans 15 daily departures. According to Cirium Diio, it will overtake KLM as the 12th largest operator in the market.

Gatwick and Heathrow joined its network in 2021, followed by Amsterdam and Paris CDG in 2023, Edinburgh in 2024, and Dublin and Madrid in 2025. In 2026, Barcelona and Milan will be served.

Not coincidentally, Delta only began flying from Boston to Barcelona and Milan in 2025. Having not had Milan flights between 2009 and 2024, Boston will now have two operators. Despite wanting to fly to Lisbon, JetBlue has still not confirmed any route. However, WestJet will begin Halifax-Lisbon flights, albeit with a highly unusual schedule to overcome the chronic lack of slots.

JetBlue currently plans nine routes from Boston, with the remaining five being from JFK. Next July, Cirium data shows the carrier will have nine daily departures from Boston to Europe, although it will still be second to its core competitor, Delta Air Lines. JetBlue’s share of the Massachusetts airport’s European offering has risen to a record 15%. Of course, the airline’s fairly low-capacity narrowbodies mean it has a smaller share of the total seats for sale.

Next July, four of JetBlue’s European routes are currently scheduled on less premium and higher-capacity Airbus A321neos. Things could change, so this reflects what is known as of November 21. Some 160 seats per flight will be available. This comprises 16 fully enclosed Mint suites (1-1), along with 42 seats in Even More Space (3-3; 35″ to 37″ pitch), and 102 seats in the bog-standard Core (3-3; 32″ pitch).

This configuration will be flown from Boston to Dublin, Edinburgh, and Glasgow, and from JFK to Dublin. Last July, the 160-seater was also deployed from JFK to Edinburgh. However, this route, which started in May 2024, will switch to the low-capacity, high-premium, 138-seat A321LR. That configuration was last flown from the Big Apple to Scotland’s capital in 2024. The 138-seater has 24 fully enclosed Mint suites, 24 Even More Space seats (3-3; 35″), and just 90 seats in Core (3-3; 32″).

What About This Possible Future Route?

First, some context is needed. In the 12 months to September 2025, approximately 57,000 round-trip passengers flew between Boston and Milan, which will now have two airlines—JetBlue and Delta. In contrast, Boston to Geneva had about 38,000 passengers, which is a reasonable foundation on which to build. It has not been served before.

Boston to Milan had an average one-way fare across all airlines, cabins, and passengers of 31 US cents per nautical mile (including a fuel surcharge). The increased competition will likely reduce this going forward, which is great for customers. In contrast, Geneva was much higher—44 US cents per nautical mile. JetBlue would, of course, carry passengers across the US via Boston.

The much higher result reflects more premium travelers, a higher average fare, and a shorter distance, the latter helping with lower operational expenses. Could this route appeal to JetBlue? Delta ended JFK-Geneva flights in October, so that market now only has SWISS, along with United from Newark.
