How 5O840 actually runs
Pro Flight Search has tracked every published board update for 5O840 across the OPO and CDG boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~21 min) but landed right on schedule. Not enough to call it.
