How CZ3255 actually runs

Pro Flight Search has tracked every published board update for CZ3255 across the SZX and SHA boards: schedule changes, gate pushes and actual clocks. Usually lands ~8 min early. Based on 14 confirmed landings · 13/14 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how CZ3255 operates rather than what the timetable promises. Numbers refresh as new flights operate.
