The U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS) reported today that U.S. airlines carried 67.1 million systemwide (domestic + international) scheduled service passengers in June 2013, 0.7 percent more than in June 2012. The systemwide increase was the result of a 0.1 percent increase in the number of domestic passengers (58.0 million) and a 4.4 percent increase in international passengers (9.1 million) (Tables 1, 7, 13).

BTS, a part of the Department’s Research and Innovative Technology Administration, reported that U.S. airlines carried 0.5 percent more total systemwide passengers during the first six months of 2013 (365.7 million) than during the same period in 2012 (Table 2). Domestically, U.S. airlines carried 317.8 million passengers, 0.2 percent more than 2012 (Table 8). Internationally, they carried 47.9 million passengers, up 2.4 percent from 2012 (Table 14). See Tables 2, 8 and 14 of Air Traffic Press Releases for previous-year data.

The June 2013 systemwide load factor of 87.0 percent, the domestic load factor of 87.0 percent and the international load factor of 86.8 percent were all record highs for the month of June as year-over-year growth in revenue passenger-miles exceeded both domestic and international capacity expansion (Tables 1, 7, 13). Load factor is a measure of the use of aircraft capacity that compares Revenue Passenger-Miles (RPMs) as a proportion of Available Seat-Miles (ASMs).

Reporting Notes
Data are compiled from monthly reports filed with BTS by commercial U.S. air carriers detailing operations, passenger traffic and freight traffic. This release includes data received by BTS from 74 carriers as of Sept. 10 for U.S. carrier scheduled civilian operations.

Southwest and AirTran Airways are reporting as separate carriers with the exception of their financial reports.  They have one FAA SOC (single operating certificate), requiring that they utilize the same safety/operating procedures, but they have separate DOT 401 economic certificates, meaning they remain operating as separate economic entities.
