How WN503 actually runs

Pro Flight Search has tracked every published board update for WN503 across the SMF and SNA boards: schedule changes, gate pushes and actual clocks. Usually lands on time. Based on 5 confirmed landings · 4/5 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 WN503 operates rather than what the timetable promises. Numbers refresh as new flights operate.
