How BA637 actually runs

Pro Flight Search has tracked every published board update for BA637 across the ATH and LHR boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~11 min) but landed about 33 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how BA637 operates rather than what the timetable promises. Numbers refresh as new flights operate.
