How AA621 actually runs
Pro Flight Search has tracked every published board update for AA621 across the MCO and SXM boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 22 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how AA621 operates rather than what the timetable promises. Numbers refresh as new flights operate.
