How FI551 actually runs
Pro Flight Search has tracked every published board update for FI551 across the LIS and KEF boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~39 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how FI551 operates rather than what the timetable promises. Numbers refresh as new flights operate.
