How BA639 actually runs
Pro Flight Search has tracked every published board update for BA639 across the ATH and LHR boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left noticeably late (~39 min) but landed a little late (~20 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how BA639 operates rather than what the timetable promises. Numbers refresh as new flights operate.
