How AA3546 actually runs

Pro Flight Search has tracked every published board update for AA3546 across the STL and BOS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~78 min) but landed heavily delayed (~60 min). Not enough to call it.

The verdict above is that record speaking, so it reflects how AA3546 operates rather than what the timetable promises. Numbers refresh as new flights operate.
