Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at ICN and KIX 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 TW309 actually runs
Pro Flight Search has tracked every published board update for TW309 across the ICN and KIX boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left a little late (~20 min) but landed about 7 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how TW309 operates rather than what the timetable promises. Numbers refresh as new flights operate.
