Airspace Flow Programs (AFPs) represent a new type of air traffic flow management strategy that was first introduced during the summer of 2006. They are similar to ground delay programs which are used to control arrivals into an airport, but instead control “arrivals” into some region of enroute airspace. This paper describes the functioning of AFPs, and the strategies used by National Airspace System (NAS) customers, including the swapping of flights to accommodate customer priorities and routing out of an AFP.
