How FI450 actually runs

Pro Flight Search has tracked every published board update for FI450 across the KEF and LHR boards: schedule changes, gate pushes and actual clocks. Usually lands ~7 min early. Based on 13 confirmed landings · 11/13 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how FI450 operates rather than what the timetable promises. Numbers refresh as new flights operate.
