How B6870 actually runs

Pro Flight Search has tracked every published board update for B6870 across the FLL and BOS boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left a little late (~19 min) but landed about 24 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how B6870 operates rather than what the timetable promises. Numbers refresh as new flights operate.
