Delta Air Lines is adding transAtlantic services from Boston to Europe, with brand-new nonstop flights to Madrid and Nice in mid-May 2026. Services to Madrid will operate daily, and three times weekly to Nice, commencing 16 and 17 May respectively.
With these additions, Delta will now serve 12 European destinations from Boston, offering travellers unrivaled global coverage and more ways to connect across the continent.
Further enhancing this network, Delta’s expanded service to Barcelona and Milan adds even more options for Boston travellers. Daily flights to Barcelona begin 7 May, and four-times-weekly service to Milan begin 16 May, both launching earlier than in 2025 to better align with seasonal demand and provide greater flexibility.

“As Boston’s leading airline, Delta plays a vital role in connecting the city to the world,” said Paul Baldoni, Senior Vice President of Network Planning. “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.”
In the span of two decades, Delta has nearly tripled its service in Boston, growing from 25 to approximately 70 destinations worldwide. Together with its partners, Delta now connects Boston to four continents, offering around 20 daily international flights.
Delta’s new flights to Madrid and Nice will be operated by the Airbus A330-900neo, featuring four product experiences including Delta One® up the front.
