A year of window seats

We flew every route on every day of 2026, at ten departure times a day: 73,000 simulated flights, each worked out minute by minute by the same engine as the planner, on an approximate great-circle path.

Winter means January, February, November and December; afternoon means 13:00, 15:00 and 17:00 departures, local time. Real flights bend with winds and air traffic control, so treat these as strong tendencies.
