How JU4211 actually runs
Pro Flight Search has tracked every published board update for JU4211 across the LHR and BEG boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left heavily delayed (~77 min) but landed noticeably late (~44 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how JU4211 operates rather than what the timetable promises. Numbers refresh as new flights operate.
