Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at IAH and LGA 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.
Under low visibility at LGA, United Airlines has historically cancelled ~17% of flights, vs 4.3% in clear conditions, over the trailing 90 days.
