How AA1520 actually runs

Pro Flight Search has tracked every published board update for AA1520 across the LAS and ORD boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left right on schedule but landed about 20 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA1520 operates rather than what the timetable promises. Numbers refresh as new flights operate.
