Up To 17-Hour Nonstop Flights: Delta’s 10 New Ultra-Long Routes In 2026

Delta Air Lines has the world’s third-highest number of long-haul flights this year, after United Airlines and Emirates. Across the whole of 2026, the SkyTeam member plans an average of 113 daily departures from the US (double for both ways). Unsurprisingly, Europe accounts for the vast bulk of such activity, with 63% of its long-haul services there.
