A January 1982 letter from the FAA's Northwest Region to the Port of Seattle reviews a draft aviation demand forecast for Boeing Field (BFI) prepared for the SEA/BFI Airspace Study. The FAA requests that the final report include more detailed aircraft mix data by class, a full list of assumptions behind the forecasts (such as economic conditions, fuel costs, and general aviation trends), and a clear indication that the projections are unconstrained. The agency also recommends presenting both high and low forecast ranges to account for uncertainty, particularly in long-range general aviation projections.

In a December 28, 1981 memorandum from Boeing Field/King County International Airport, Airport Manager Donald W. Smith responds to a Port of Seattle representative regarding the forecasting methodology for aviation demands at BFI. Smith confirms that the proposed approach is consistent with prior discussions and historical statistics, and acknowledges that, given limited current information and resources, the methods and sources used are acceptable.
