On July 14, 2008, the DOT Office of the Secretary and FAA published amendments to the 1996 Policy Regarding the Establishment of Airport Rates and Charges. In amending the Rates and Charges Policy, the DOT and FAA (1) clarified that airport proprietors may impose a landing fee that incorporates both weight-based and per-operation elements; and (2) expanded an airport sponsor’s ability to include among the airfield charges during congested hours at congested airports the cost of airfield projects under construction and the costs of a secondary airport.
