How AA78 actually runs
Pro Flight Search has tracked every published board update for AA78 across the DFW and LHR boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left right on schedule but landed about 28 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how AA78 operates rather than what the timetable promises. Numbers refresh as new flights operate.
