STEM contains a model of Global Air Travel that covers 100% of commercial airports in the U.S. and about 80% of commercial airports world wide. The model was calibrated using data on individual tickets within the United States for all of 2007 from the U. S. Department of Transportation Research and Innovative Technology Administration Bureau of Transportation Statistics (RITA-BTS). Tickets give the origin and destination of full trips, rather than individual flights. The RITA-BTS ticket data (DB1BTicket from the Airline Origin and Destination Survey) are a sample of 10% of U.S. tickets from reporting carriers in that year. A complete description of the model is given in the following paper: The Cost of Simplifying Air Travel When Modeling Disease Spread
