How SQ34 actually runs
Pro Flight Search has tracked every published board update for SQ34 across the SIN and SFO boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left right on schedule but landed about 39 min early. Not enough to call it.
