Overview
London Heathrow to Johannesburg — north-south long-haul where the duration matters but the time-zone shift barely does. Treat it as a sleep-and-circulation problem, not a jet-lag one.
Jet lag
Only 1-hour TZ shift — almost no circadian jet lag. The fatigue is from cabin block time, not phase shift. Hydration, compression socks, and a real sleep window are the priorities.
Build a LHR→JNB adaptation scheduleBest window side
Mostly southbound with a slight east lean — the left (east) side gets sunrise over Africa; for sleep, the side that lets you fully blind the window matters more.
Cabin humidity
A350-1000 is the comfort pick on this route. 777-300ER is acceptable but drier on an 11-hour overnight. A330-300 sits in between.
