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