How A3863 actually runs
Pro Flight Search has tracked every published board update for A3863 across the VIE and ATH boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left heavily delayed (~46 min) but landed a little late (~18 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how A3863 operates rather than what the timetable promises. Numbers refresh as new flights operate.
