How LH491 actually runs

Pro Flight Search has tracked every published board update for LH491 across the SEA and FRA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed -6 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how LH491 operates rather than what the timetable promises. Numbers refresh as new flights operate.
