Why Do So Many Long-Haul Flights Leave at Night?

Every night, thousands of planes cross the globe while most of us are asleep. Many long-haul flights leave late in the evening—not because aircraft need darkness, but because airlines are working backward from the time those flights must arrive. A departure from New York at 10:00 p.m. can reach London the following morning, giving passengers access to onward connections and leaving the aircraft enough time for its next operation. Behind that single departure time are time zones, airport slots worth millions of dollars, night restrictions, connecting flights, aircraft schedules, delays, and high-altitude winds. This video explains how all of those parts fit together—and why the pattern mainly appears on eastbound flights crossing several time zones.
