The northern aviation winter season is nearly here. Based on IATA slots, northern carriers, including Delta Air Lines, will switch to winter schedules on October 26. They'll maintain them until March 28. According to Cirium Diio data, Delta will have the world's fifth-highest number of long-haul services in this period. Only Emirates, United Airlines, Qatar Airways, and British Airways will have more.

Given Delta's vast size, just one in 25 of its flights will be long-haul. This is despite its winter long-haul services rising by 3% year-over-year to their highest level yet. They're up by over a fifth compared to before the pandemic in winter 2019/2020. But what about the SkyTeam member's longest nonstop operations?
