How UA3459 actually runs

Pro Flight Search has tracked every published board update for UA3459 across the IAD and PWM boards: schedule changes, gate pushes and actual clocks. Usually lands on time. Based on 11 confirmed landings · 11/11 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 UA3459 operates rather than what the timetable promises. Numbers refresh as new flights operate.
