How UA1100 actually runs

Pro Flight Search has tracked every published board update for UA1100 across the LAX and SAN boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left noticeably late (~30 min) but landed about 10 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA1100 operates rather than what the timetable promises. Numbers refresh as new flights operate.
