How WN3509 actually runs

Pro Flight Search has tracked every published board update for WN3509 across the MCO and STL boards: schedule changes, gate pushes and actual clocks. Usually lands ~17 min early. Based on 9 confirmed landings · 9/9 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 WN3509 operates rather than what the timetable promises. Numbers refresh as new flights operate.
