How UA1938 actually runs

Pro Flight Search has tracked every published board update for UA1938 across the IAD and PHX boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left a little late (~13 min) but landed about 41 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA1938 operates rather than what the timetable promises. Numbers refresh as new flights operate.
