How BA203 actually runs

Pro Flight Search has tracked every published board update for BA203 across the LHR and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left noticeably late (~21 min) but landed about 21 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how BA203 operates rather than what the timetable promises. Numbers refresh as new flights operate.
