How UA5543 actually runs

Pro Flight Search has tracked every published board update for UA5543 across the JAC and DEN boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~35 min) but landed about 9 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA5543 operates rather than what the timetable promises. Numbers refresh as new flights operate.
