How BA852 actually runs

Pro Flight Search has tracked every published board update for BA852 across the LHR and PRG boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~22 min) but landed about 5 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how BA852 operates rather than what the timetable promises. Numbers refresh as new flights operate.
