Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at IST and SOF 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.
