How CZ657 actually runs

Pro Flight Search has tracked every published board update for CZ657 across the CAN and SFO boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left a little late (~15 min) but landed about 11 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how CZ657 operates rather than what the timetable promises. Numbers refresh as new flights operate.
