How FB437 actually runs
Pro Flight Search has tracked every published board update for FB437 across the SOF and FRA boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~90 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how FB437 operates rather than what the timetable promises. Numbers refresh as new flights operate.
