How JL8 actually runs

Pro Flight Search has tracked every published board update for JL8 across the NRT and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~8 min) but landed about 25 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how JL8 operates rather than what the timetable promises. Numbers refresh as new flights operate.
