How BA850 actually runs
Pro Flight Search has tracked every published board update for BA850 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 a little late (~8 min) but landed about 21 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how BA850 operates rather than what the timetable promises. Numbers refresh as new flights operate.
