Delta is preparing for its most expansive transatlantic schedule to date. After months of adding new routes, reinforcing major US gateways and elevating its premium offerings, the airline is poised to deliver an unforgettable European travel season in 2026. While the Atlanta-based carrier trails United Airlines in the number of European cities it serves, Delta has been making some interesting additions and this continues into next summer.
Delta’s summer 2026 lineup introduces new nonstop routes designed for every type of traveler. From historic capitals to Mediterranean escapes, customers have seven new direct options for exploring Europe. These include:
- Boston Logan International Airport (BOS) to/from Adolfo Suárez Madrid-Barajas Airport (MAD) (daily; starts on May 6th) Iberia and JetBlue also fly this route nonstop.
- Boston Logan International Airport (BOS) to/from Nice Côte d’Azur Airport (NCE) (3x weekly; starts on May 16th)
- New York John F Kennedy International Airport (JFK) to/from Malta International Airport (MLA) (3x weekly; starts on June 7th)
- New York John F Kennedy International Airport (JFK) to/from Olbia-Costa Smeralda-Prince Karim Aga Khan IV Airport (OLB) (4x weekly; starts on May 20th)
- New York John F Kennedy International Airport (JFK) to/from Porto’s Francisco Sá Carneiro Airport (OPO) (daily; starts on May 21st)
- Seattle-Tacoma International Airport (SEA) to/from Josep Tarradellas Barcelona-El Prat Airport (BCN) (3x weekly; starts on May 7th)
- Seattle-Tacoma International Airport (SEA) to/from Leonardo da Vinci Rome Fiumicino Airport (FCO) (4x weekly; starts on May 6th) This will go head to head with Alaska Airlines’ new Rome service (Alaska has bumped this to a daily service before launch in preparation for this fight).
These new flights join an already fast-growing portfolio. In summer 2026, Delta will operate more than 650 weekly departures to nearly 30 European destinations, marking the largest transatlantic schedule in the airline’s history. Seasonal favorites, including Catania-Fontanarossa Airport (CTA) in Sicily will return in April 2026 to round out the network.
Delta’s expansion goes hand-in-hand with elevated customer experiences. Highlights for transatlantic travelers in 2026 include:
- The largest lounge footprint of any US airline, with 56 Delta Sky Clubs® totaling more than 700,000 square feet globally
- Dedicated Delta One® Lounges in Boston Logan International Airport (BOS), Los Angeles International Airport (LAX), New York John F Kennedy International Airport (JFK), and Seattle-Tacoma International Airport (SEA)
- Increased deployment of widebody aircraft, offering Delta One®, Delta Premium Select, and Delta Comfort
- A new culinary collaboration with chef José Andrés, featuring Spanish-inspired dishes and curated wine pairings in select premium cabins
Anthony’s Take: I’m excited for Delta’s summer 2026 schedule. Some of these flights are on my radar for when I begin planning my summer trips to Europe.
