How WN4394 actually runs

Pro Flight Search has tracked every published board update for WN4394 across the HOU and BWI boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 9 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN4394 operates rather than what the timetable promises. Numbers refresh as new flights operate.
