How UA550 actually runs

Pro Flight Search has tracked every published board update for UA550 across the YYC and DEN boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: landed +14 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA550 operates rather than what the timetable promises. Numbers refresh as new flights operate.
