How BT851 actually runs
Pro Flight Search has tracked every published board update for BT851 across the TLL and BRU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left a little late (~9 min) but landed about 6 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how BT851 operates rather than what the timetable promises. Numbers refresh as new flights operate.
