live boardsHow UL121 actually runs
Pro Flight Search has tracked every published board update for UL121 across the CMB and MAA boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed +26 min. Not enough to call it.
The verdict above is that record speaking, so it reflects how UL121 operates rather than what the timetable promises. Numbers refresh as new flights operate.
