live boardsHow BI121 actually runs
Pro Flight Search has tracked every published board update for BI121 across the BWN and MAA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: landed +4 min. Not enough to call it.
The verdict above is that record speaking, so it reflects how BI121 operates rather than what the timetable promises. Numbers refresh as new flights operate.
