How BA861 actually runs

Pro Flight Search has tracked every published board update for BA861 across the PRG and LHR boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left a little late (~13 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how BA861 operates rather than what the timetable promises. Numbers refresh as new flights operate.
