How WS559 actually runs

Pro Flight Search has tracked every published board update for WS559 across the YUL and YYC boards: schedule changes, gate pushes and actual clocks. Usually lands ~29 min early. Based on 3 confirmed landings · 3/3 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 WS559 operates rather than what the timetable promises. Numbers refresh as new flights operate.
