BTS 57-13 Friday, December 13, 2013 Contact: Dave Smallen Tel: 202-366-5568 BTS Releases September 2013 U.S. Airline Traffic Data; Systemwide Passengers Up 0.9 Percent from September 2012 The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today that U.S. airlines carried 58.0 million systemwide (domestic + international) scheduled service passengers in September 2013, 0.9 percent more than in September 2012. The systemwide total was the result of a 0.8 percent increase in the number of domestic passengers (50.5 million) and a 1.9 percent increase in international passengers (7.4 million). BTS, a part of the Department’s Research and Innovative Technology Administration, reported that U.S. airlines carried 0.4 percent more total systemwide passengers during the first nine months of 2013 (560.6 million) than during the same period in 2012. Domestically, U.S. airlines carried 485.8 million passengers, up 0.1 percent from 2012. Internationally, they carried 74.8 million passengers, up 3.0 percent from 2012. See Tables 2, 8 and 14 of Air Traffic Press Releases for previous-year data. Systemwide and domestic load factors rose in September 2013 from a year earlier but remained below the all-time September highs reached in 2011. In both cases, growth in Revenue Passenger-Miles (RPMs) exceeded growth in capacity, measured by Available Seat-Miles (ASMs). The September 2013 international load factor declined from September 2012 as capacity increased more than the growth in revenue passenger-miles. Load factor is a measure of the use of aircraft capacity that compares RPMs as a proportion of Available Seat-Miles ASMs. Top Airlines In September, Delta Air Lines carried more systemwide passengers than any other U.S. airline. Southwest Airlines carried the most domestic passengers while United Airlines carried the most international passengers. The top 10 U.S. airlines in terms of number of passengers carried 80.2 percent of systemwide passengers, unchanged from 80.2 percent carried by the U.S. airlines that were in the top 10 in September 2012.
