When two aircraft were deliberately flown into the World Trade Center in New York City on September 11, 2001, the aviation industry changed forever. The Federal Aviation Administration and the new Department of Homeland Security changed the regulations regarding the aviation industry, and some of the bystanders throughout this process were the airports. Revenues decreased while expenses increased, creating a very difficult financial situation for the airports. The country was divided into four regions and one airport from each of the three airport hub categories was selected for each region through a stratified random sampling process. Financial data for the time period 2000-2003 for the airports selected was collected and analyzed to find the financial impact that September 11, 2001 had on the airports. Throughout the research it became clear that all airports were financially affected by September 11, 2001; and that the geographical location played a role in the financial impact. Airports in the west regions were less affected than airports in the northeast or midwest regions.
