Why Fly From America to Europe at Night?
The biggest reason is surprisingly simple:
Time zones.
Imagine leaving New York in the evening.
You board around 7 or 8 p.m., have dinner, settle into your seat, and sleep for much of the flight. Several hours later, you arrive in London or Paris in the morning.
From the passenger’s perspective, the schedule makes sense.
Instead of spending an entire daylight day sitting on an airplane, you travel while you would normally be sleeping and arrive at your destination with most of the day still ahead of you.
The same scheduling logic has been part of transatlantic aviation for decades. Research on the North Atlantic traffic system describes the pattern as predominantly westbound during the day and eastbound overnight because of the combination of time-zone differences and flight times.
