How CX2255 actually runs
Pro Flight Search has tracked every published board update for CX2255 across the HKG and LHR boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left right on schedule but landed about 18 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how CX2255 operates rather than what the timetable promises. Numbers refresh as new flights operate.
