How AA1638 actually runs
Pro Flight Search has tracked every published board update for AA1638 across the PHX and DEN boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~55 min) but landed a little late (~9 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how AA1638 operates rather than what the timetable promises. Numbers refresh as new flights operate.
