This article is a continuation of the part one article " New Methods to Forecast Passenger Demand. Part 1"  We'll pick up right where we left off with the results of the processes suggested in part one.

The successful, yet tedious, implementation of the neural network to each of the five scenarios produced varying results.  Due to the tremendous effect September 11, 2001, had on U.S. domestic air travel, the resultant mean average error was calculated for the entire data population encompassing the years 2000 through Q3, 2005; however, the year including September 11, 2001 (Q3 2001 - Q2 2002), was extracted to identify how much prediction error was attributable specifically to that highly unpredictable period.  Even though the hypothesis was not fully supported by the data, this categorization of results should provide further insight as will be discussed later.
