From Timothy Gerla:
AirportStatus displays a quick view of airport delays and closures across the United States, as well as some major airports in Canada. Use it during your travels to anticipate delays due to weather, traffic, or any other airport problems. Data comes from the FAA.This version is ad-supported. There will be an ad-free version available for purchase soon, called AirportStatus.This application does NOT report specific flight delays. It displays information on airport-wide delays.For my Canadian users, only SOME airports are reported by the USA FAA. These airports will show up, but any others won't.
