Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at VIE and DBV are near their clear-air norm right now, so this reflects the route's recent baseline rather than a weather penalty. These figures come from both airports' records under conditions like today's, over the last 90 days. This route has few tracked flights so far, so treat this as an early read.

How OS621 actually runs
Pro Flight Search has tracked every published board update for OS621 across the VIE and DBV boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 3 completed legs so far: left a little late (~15 min) but landed about 5 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS621 operates rather than what the timetable promises. Numbers refresh as new flights operate.
