BOSTON- Delta Air Lines (DL) is expanding its transatlantic network from Boston Logan International Airport (BOS) with two new nonstop routes. Service to Madrid (MAD) begins May 16, while flights to Nice (NCE) launch May 17, giving Boston travelers more direct access to Spain and the French Riviera.
With these additions, Delta (DL) strengthens its role as Boston’s leading global carrier, offering nonstop flights to 12 European destinations in summer 2025. The airline is also growing its seasonal schedules to Barcelona (BCN) and Milan (MXP), improving connectivity and aligning with peak demand.

The launch of Boston–Madrid and Boston–Nice marks a significant expansion of Delta’s European portfolio.
Travelers can expect daily service to Madrid and three weekly flights to Nice on Tuesdays, Thursdays, and Saturdays.
Both routes will be operated with the Airbus A330-900neo, equipped with four cabin options, including Delta One® suites with lie-flat seating and premium amenities.
These flights add variety to Boston’s transatlantic network. Madrid offers historic boulevards, world-class art, and culinary traditions, while Nice connects travelers to the French Riviera’s Mediterranean coastline and culture.
Beyond these cities, Delta’s SkyTeam partners provide convenient onward connections across Europe.

In addition to Madrid and Nice, Delta is boosting its seasonal European network with earlier starts to Barcelona and Milan. Daily Boston–Barcelona flights begin May 7, while four-times-weekly Boston–Milan flights start May 16.
These adjustments better align with seasonal demand and give travelers more flexibility when planning spring and summer trips.
Together, these routes position Boston as a premier U.S. gateway to Southern Europe, offering direct access to key leisure and business destinations.
