How UA754 actually runs

Pro Flight Search has tracked every published board update for UA754 across the BOS and SFO boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left heavily delayed (~56 min) but landed about 25 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA754 operates rather than what the timetable promises. Numbers refresh as new flights operate.
