How WJ3979 actually runs

Pro Flight Search has tracked every published board update for WJ3979 across the GRU and EZE boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: landed -3 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how WJ3979 operates rather than what the timetable promises. Numbers refresh as new flights operate.
