Conditions at TPE and IAD are near their clear-air norm right now, so this reflects the route's recent baseline rather than a weather penalty. For this route and airline, under conditions like today's, over the last 90 days. This route's tracked sample is still thin — treat these as an early read, not a precise forecast.

How BR4 actually runs

Pro Flight Search has tracked every published board update for BR4 across the TPE and IAD boards: schedule changes, gate pushes and actual clocks. Usually lands ~15 min early. Based on 8 confirmed landings · 8/8 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 BR4 operates rather than what the timetable promises. Numbers refresh as new flights operate.
