Delta Air Lines is expanding its European network for the 2027 summer season with the addition of a new route connecting Boston Logan International Airport to Reykjavik Keflavik International Airport. The carrier, which currently holds the position of the second-largest operator on the transatlantic corridor, has confirmed four new or returning routes across the North Atlantic for next year.
This latest addition marks a strategic shift for the airline. It will operate the Boston to Reykjavik leg using a Boeing 757, giving Delta three such aircraft on European routes for the first time in four years. While the carrier has historically expressed reluctance to fly narrowbody jets across the Atlantic, this specific route fits within its broader operational adjustments for the region.
Boston to Reykjavik Service Details
According to OAG data, Delta will reintroduce service from Boston to Iceland starting in April 2027. The airline previously operated this route on a seasonal basis between May and September 2021, utilizing the Boeing 757-200 with up to daily flights during that period.
The 2,097 nautical mile journey will become Delta’s shortest route to Europe. This relaunch brings the total number of Delta routes to Iceland to four. The airline already serves the country from Detroit Metropolitan Airport, which began in 2023; Minneapolis-St. Paul International Airport, which started in 2016; and New York’s John F. Kennedy International Airport, which launched in 2011.
Competition in this market will intensify. Icelandair will continue to serve the route, and the market previously hosted the now-defunct low-cost carrier PLAY in 2025. Delta aims to capture US point-of-sale travelers, loyalty program members, and passengers connecting in Boston to other domestic destinations.
Expanding Boston’s European Network
The addition of the Iceland route complements other recent announcements from Delta. The carrier is also adding Venice Marco Polo Airport to its schedule from Boston. These expansions contribute to a significant increase in capacity from Boston to Europe next summer.
Booking data for the 12 months leading to August 2026 showed that Venice was the largest unserved European airport from Boston, with 47,000 round-trip indirect passengers. Most of this traffic occurred between May and August. By adding Venice and Reykjavik, Delta will operate 14 routes from Boston to Europe next summer.
In July 2027, Delta plans 14 daily departures to Europe from Boston. This represents a 17% increase over the previous record set in July 2026. The airline will hold a 26% share of all Boston to Europe services, widening its lead over second-place carrier JetBlue, which holds a 17% share.
While Delta focuses on Southern European destinations like Venice, other carriers are targeting different markets. Icelandair will launch flights from Reykjavik to St. Louis on May 14, 2027. This will be a four-weekly service using a 160-seat Boeing 737 MAX 8. The market was last served by the now-defunct WOW Air in 2019.
American Airlines is also returning to Iceland. The carrier will begin daily flights from Philadelphia to Reykjavik on May 27, 2027. These flights will use a 196-seat Airbus A321neo. This marks American’s return to Iceland after last flying there in 2019 from Dallas/Fort Worth. Philadelphia to Reykjavik was previously served by Icelandair until 2020.
