How UA442 actually runs

Pro Flight Search has tracked every published board update for UA442 across the SFO and SAN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left right on schedule but landed about 33 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA442 operates rather than what the timetable promises. Numbers refresh as new flights operate.
