How UA1145 actually runs
Pro Flight Search has tracked every published board update for UA1145 across the SFO and CUN boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left noticeably late (~22 min) but landed a little late (~10 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how UA1145 operates rather than what the timetable promises. Numbers refresh as new flights operate.
