A network built on continued growth
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.
Can’t wait for summer ’26? Winter adventures are calling
For customers looking to head abroad before summer arrives, Delta’s winter schedule offers a wide 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, Paris’s elegant streets, 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.
The journey, elevated: What to expect on the ground and in the air
Delta’s growth isn’t just about more places, it’s about a more premium experience at every step. 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.
- 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
- Industry-leading inflight entertainment, including Delta’s new partnership with YouTube that gives customers frictionless, ad-free access to a selection of popular 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.
Whether customers are planning a winter getaway or looking ahead to next summer, Delta offers more ways than ever to make their next international trip unforgettable.
