Delta is adding more nonstop flights between Boston and Europe next summer with the launch of two new routes. The Atlanta based carrier is adding flights from the Massachusetts city to Madrid (MAD) and Nice (NCE).
Delta is Expanding its International Footprint in Boston
With the two new routes, Delta will now serve 12 European destinations from Boston. Service to Madrid will operate daily, beginning May 16, 2026 while service to Nice launches 3x weekly, on Tuesdays, Thursdays, and Saturdays, on May 17, 2026.
Delta will operate both routes with Airbus A330-900neo aircraft outfitted with 29 Delta One suites, 28 Premium Select seats, 56 Comfort+ seats, and 168 Main Cabin seats.

Paul Baldoni, Senior Vice President of Network Planning at Delta, said this about the launch of the new routes:
“As Boston’s leading airline, Delta plays a vital role in connecting the city to the world. By adding nonstop service to Madrid and Nice, we’re enhancing our European network and continuing our commitment to providing an exceptional travel experience from start to finish.”
Massport CEO Rich Davey added:
“We appreciate our partnership with Delta and are thrilled about their plans to grow their operations at Boston Logan with these new offerings to Spain and France, including Nice which will be our 60th international destination. Starting next spring, these flights offer our passengers even more options to travel to Europe for business or pleasure. With over 130 destinations to choose from and a new focus on improving the customer experience, Boston Logan is going above and beyond to meet passenger needs.”
Along with the new Madrid and Nice flights, Delta is also expanding service from Boston to Barcelona (BCN) and Milan (MXP). Daily flights to Barcelona launch on May 7, 2026 and 4x weekly service to Milan begins May 16, 2026. Both of these routes are launching earlier than in previous years.
The carrier has also expanded its premium offerings in Boston with the opening of a new, albeit small, Delta One Lounge at the airport. For reference, Air France and KLM Business Class passengers, which typically would have access to Delta One Lounges, must use the Air France lounge in Boston.

My Thoughts
Delta has been rapidly growing in Boston and now flies from the airport to approximately 70 destinations around the world. Along with its partners, Delta now connects Boston to four continents. Two decades ago, when Delta first started building up its Boston hub, it served only 25 destinations.
As an Austin resident, where Delta just announced new service bringing us up to roughly 30 destinations, I’m hopeful that the rapid expansion we’ve seen from Delta in Boston and Seattle will be replicated in my own backyard. A new concourse is under construction and it appears that Delta and Southwest will be battling it out for supremacy.
Summary
Delta is expanding its footprint once again in Boston with the launch of two new transatlantic routes. Beginning next summer, Delta will connect the city to Madrid and Nice along with increased service to Barcelona and Milan.
