How SY8770 actually runs

Pro Flight Search has tracked every published board update for SY8770 across the MKC and STL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: landed +8 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how SY8770 operates rather than what the timetable promises. Numbers refresh as new flights operate.
