Why the SF to London flight is rough

Ten hours. Eight time zones. A lunchtime landing into a 4am body.

Takeoff is early evening San Francisco. London is already past 1am. Cabin dinner hits around 90 minutes in, then a long sleep block. You land mid-morning to lunchtime London with a body that thinks it’s the middle of the night. The eight-hour shift is the biggest most travelers handle in a single overnight.

One step from the path

Eat the dinner. Then sleep long.

On the San Francisco to London flight, the cabin dinner is part of the rhythm. Ten hours is enough that the meal lines up with London dinnertime by your body’s reckoning. Eat it, then settle for a long sleep block when the lights dim. Mask, headphones, eyes closed. Wake to a light breakfast and English morning.

That’s one card. The path has the rest. The nights before. The morning of. The crossing. Your first afternoon in London.
