The Department of Transportation (DOT) has added a helpful travel tool to its Web site: the real-time airport status page. By visiting http://www.fly.faa.gov/index.html, you can check for air traffic delays at 40 American airports or even more airports if you search by region. What makes this site particularly unique as well as valuable is the in-depth and up-to-the-minute accuracy of its delay information, which includes delays by destinations, general departure delays, and general arrival delays.
