Why the Boston to London red-eye is rough

Six hours. Five time zones. A 7am landing into a 2am body.

Takeoff is 7–10pm Boston. London is already past 1am. The cabin dinner arrives while London sleeps. You get maybe three hours of useful sleep before the cabin lights come up. You land into a 7am London that feels like 2am to your body. Short flight, sharp jet lag.
