How WS1501 actually runs

Pro Flight Search has tracked every published board update for WS1501 across the SFO and YYC 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 13 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WS1501 operates rather than what the timetable promises. Numbers refresh as new flights operate.
