How AA2878 actually runs

Pro Flight Search has tracked every published board update for AA2878 across the PHL and DEN boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left about 8 min early but landed about 32 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA2878 operates rather than what the timetable promises. Numbers refresh as new flights operate.
