How TS339 actually runs
Pro Flight Search has tracked every published board update for TS339 across the LGW and YUL boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left a little late (~15 min) but landed about 26 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how TS339 operates rather than what the timetable promises. Numbers refresh as new flights operate.
