Overview
San Francisco to Hong Kong — one of the main US-Asia corridors, usually flown by composite aircraft. Westbound dateline crossing makes the jet-lag math friendlier than the raw TZ math.
Jet lag
Crosses the dateline — calendar shifts a day forward, but the body experiences this as roughly a 9-hour westward delay. Stay up into the local evening on arrival, get afternoon light, and the body catches up faster than the clock suggests.
Build a SFO→HKG adaptation scheduleBest window side
Westbound across the Pacific — the right (north) side is the shadier choice through the long daylit cruise.
Cabin humidity
Cathay's A350-1000 is the comfort pick on this sector. United's 787-9 is the next-best. A 777-300ER is workable but drier for 14 hours.
