How UA2348 actually runs

Pro Flight Search has tracked every published board update for UA2348 across the BOS and DEN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left right on schedule but landed about 11 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA2348 operates rather than what the timetable promises. Numbers refresh as new flights operate.
