How WN1571 actually runs

Pro Flight Search has tracked every published board update for WN1571 across the DEN and MDW boards: schedule changes, gate pushes and actual clocks. Usually lands on time. Based on 9 confirmed landings · 8/9 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 WN1571 operates rather than what the timetable promises. Numbers refresh as new flights operate.
