Over the past several months, Delta Air Lines has charted new routes, strengthened key U.S. gateways and enhanced premium touches onboard and on the ground. This momentum defines the airline’s biggest transatlantic schedule yet and sets the stage for an unforgettable summer 2026.
Summer Travel
Delta has been steadily adding new pins to the map for next summer, and the full summer 2026 lineup now offers an entirely fresh menu of travel options. Whether customers are chasing history, sunshine or seaside aperitivo hour, there’s a Delta flight for every kind of adventure.
- Boston (BOS)–Madrid (MAD), launching May 6, 2026 – A city that blends centuries of art and architecture with late-night tapas and endless plazas, Madrid turns every day into a masterpiece.
- Seattle (SEA)–Rome (FCO), launching May 6, 2026 – From iconic ruins to gelato on cobblestone streets, Rome needs no introduction—and it’s now just one nonstop flight from Seattle.
- Seattle (SEA)–Barcelona (BCN), launching May 7, 2026 – Barcelona never plays it safe. Gaudí’s wonders, buzzing beaches and Catalan culture give this city its unmistakable energy.
- Boston (BOS)–Nice (NCE), launching May 16, 2026 – Landing on the French Riviera sets the tone: palm-lined promenades, turquoise water and the kind of glamor only the Côte d’Azur can deliver.
- New York (JFK)–Olbia, Sardinia (OLB), launching May 20, 2026 – With rugged cliffs, hidden coves and endless blues, Sardinia looks straight out of a postcard.
- New York (JFK)–Porto (OPO), launching May 21, 2026 – Old-world charm meets riverside views in Porto, where colorful streets meet the Douro and port wine is a way of life.
- New York (JFK)–Malta (MLA), launching June 7, 2026 – Sun-soaked coasts, ancient fortresses and Mediterranean culture shaped by Europe and North Africa, Malta feels like nowhere else on earth.
These routes join a transatlantic network that’s been expanding throughout the year. In summer 2026, Delta will operate over 650 weekly flights to nearly 30 destinations across Europe, marking the largest transatlantic schedule in Delta’s history and offering unmatched choice and connectivity across its hubs. Seasonal favorites like Catania, Italy (CTA) also return in April 2026, rounding out a summer map designed for explorers, foodies, beach-goers and anyone ready to experience something new.
Winter Adventures
For customers looking to head abroad before summer arrives, Delta’s winter schedule offers a range of options, including service to popular destinations like Amsterdam, Paris, Marrakech, London-Heathrow, Dublin, Athens and Zürich, among others.
Winter also brings its own appeal: Amsterdam’s glowing canals and cafés, the streets of Paris, London’s vibrant theater season and Dublin’s warm pub culture. Cooler months mean calmer crowds, easier access to major attractions and a more atmospheric, intimate way to explore these destinations.
Signature Service
Customers traveling across the Atlantic in 2026 will enjoy:
- The largest lounge footprint of any U.S. airline, with 56 Delta Sky Clubs featuring more than 700,000 square feet worldwide.
- Delta One Lounges in JFK, LAX, BOS and SEA, setting a new benchmark for pre-flight premium comfort.
- More widebody aircraft across transatlantic routes, giving customers access to Delta One, Delta Premium Select and Delta Comfort with added space and elevated dining.
- A new culinary collaboration with Chef José Andrés, bringing Spanish-inspired dishes and expertly curated wine pairings to select Delta One and Delta First cabins.
- In-flight entertainment, including Delta’s new partnership with YouTube that gives customers frictionless, ad-free access to a selection of YouTube creators, podcasts and music playlists. Plus, Delta has teamed up with Crunchyroll to bring the worlds of anime to Delta’s more than 165,000 seatback screens.
