How HB321 actually runs

Pro Flight Search has tracked every published board update for HB321 across the NRT and HKG boards: schedule changes, gate pushes and actual clocks. Usually lands ~7 min early. Based on 12 confirmed landings · 9/12 within 15 min of schedule. Pushes back late but makes up time in the air.

The verdict above is that record speaking, so it reflects how HB321 operates rather than what the timetable promises. Numbers refresh as new flights operate.
