How BT831 actually runs
Pro Flight Search has tracked every published board update for BT831 across the TLL and VIE boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left right on schedule but landed about 22 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how BT831 operates rather than what the timetable promises. Numbers refresh as new flights operate.
