The FAA Air Traffic Report provides a reasonable expectation of any daily impacts to normal air traffic operations, i.e. arrival/departure delays, ground stoppages, airport closures. This information is for air traffic operations planning purposes and is reliable as weather forecasts and other factors beyond our ability to control.
Always check with your air carrier for flight-specific delay information.
Today's Air Traffic Report:
Thunderstorms across the Midwest may slow air traffic in Chicago (MDW, ORD) and require cross-country flights to fly around the severe weather.
Afternoon pop-up storms in the Washington, D.C., area (BWI, DCA, IAD) also could trigger delays, while clouds are possible in Philadelphia (PHL) and Atlanta (ATL). Expect low clouds to cause delays this morning in San Francisco (SFO) and Seattle (SEA).
