How FI633 actually runs

Pro Flight Search has tracked every published board update for FI633 across the KEF and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left a little late (~6 min) but landed about 12 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how FI633 operates rather than what the timetable promises. Numbers refresh as new flights operate.
