FAAwait provides real-time access to current air traffic delays at all U.S. airports. It utilizes a data feed maintained by the FAA that tracks departure and arrival delays, ground stops, and ground delays. To access this information, an active internet connection (WiFi or cellular) is required. FAAwait does NOT provide status information for specific flights. But by monitoring airport traffic conditions, you can often anticipate delays that may impact your travel, sometimes before the airlines themselves officially update their schedules.
