How UA1099 actually runs

Pro Flight Search has tracked every published board update for UA1099 across the SJO and IAH boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: landed +7 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA1099 operates rather than what the timetable promises. Numbers refresh as new flights operate.
