How 4B863 actually runs

Pro Flight Search has tracked every published board update for 4B863 across the MSS and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed -8 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how 4B863 operates rather than what the timetable promises. Numbers refresh as new flights operate.
