How AA451 actually runs
Pro Flight Search has tracked every published board update for AA451 across the CLE and PHX 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 29 min early. Not enough to call it.
