How UA2633 actually runs

Pro Flight Search has tracked every published board update for UA2633 across the DEN and SFO 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 28 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA2633 operates rather than what the timetable promises. Numbers refresh as new flights operate.
