How UA1936 actually runs
Pro Flight Search has tracked every published board update for UA1936 across the ONT and IAH boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~31 min) but landed a little late (~8 min). Not enough to call it.
