How UA436 actually runs

Pro Flight Search has tracked every published board update for UA436 across the SFO and YYZ boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: landed +6 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how UA436 operates rather than what the timetable promises. Numbers refresh as new flights operate.
