Users can register for the free Aviation Information System service at the FAA's Web site. The site gives users specific information about airport status and why, where and when a delay is occurring and whether it will impact them, according to an FAA statement. On April 16, the FAA increased the number of airports on the site from 39 to 298, the FAA officials said.
Color codes reflect the type and severity of delay.
