How KE1023 actually runs
Pro Flight Search has tracked every published board update for KE1023 across the GMP and CJU boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~20 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how KE1023 operates rather than what the timetable promises. Numbers refresh as new flights operate.
