This story is the narrative for the Annual Passenger Seats measure. This measure indicates the maximum number of seats available for passengers to fly. These are seats scheduled, but not necessarily filled. The success of AUS and all airports is driven by passenger demand, government restrictions, and airline business models. Data on available passenger seats in the Official Airline Guide is collected and distributed by the Campbell-Hill Aviation Schedule Report. The report data is then combined to create the total annual passenger seats for the year.
