How CA843 actually runs
Pro Flight Search has tracked every published board update for CA843 across the PEK and VIE boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~10 min) but landed about 30 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how CA843 operates rather than what the timetable promises. Numbers refresh as new flights operate.
