How AA2504 actually runs

Pro Flight Search has tracked every published board update for AA2504 across the IAH and ORD boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left about 9 min early but landed about 31 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA2504 operates rather than what the timetable promises. Numbers refresh as new flights operate.
