How CZ8157 actually runs

Pro Flight Search has tracked every published board update for CZ8157 across the SZX and BKK boards: schedule changes, gate pushes and actual clocks. Usually lands ~26 min early. Based on 12 confirmed landings · 12/12 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 CZ8157 operates rather than what the timetable promises. Numbers refresh as new flights operate.
