Overview

Seoul Incheon to LAX — one of the main US-Korea corridors. The dateline math makes the body clock easier than the calendar; cabin time is still the dominant variable.

Jet lag

16-hour TZ jump, but crossing the dateline makes it feel like an 8-hour westward delay — friendlier than the raw number suggests. Stay up into LA evening, anchor afternoon light, 3-4 days for full adjustment.

Best window side

Westbound across the North Pacific — the right (north) side is the calmer pick through the daylit cruise.

Cabin humidity

Korean Air A380 upper deck and Asiana's A350-900 are the comfort picks. 777-300ER is workable on a 12-hour sector, drier than the alternatives.
