BTS, a part of DOTs Research and Innovative Technology Administration, also reported in a release of preliminary data that the system load factor of 77.6 percent and the domestic load factor of 78.1 percent were record highs for the month of January (Tables 1, 5).Tuesday, April 24, 2012 - The U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) reported today that U.S. airlines carried 54.3 million scheduled domestic and international passengers in January 2012, 1.3 percent more domestic passengers and 0.4 percent fewer international passengers than in January 2011. These changes resulted in a systemwide increase of 1.1 percent in passengers from January 2011 (Tables 1, 5, 9). The January 2012 passenger total was 3.3 percent above that of two years ago in January 2010 (Table 2).

Passenger Load Factor on All U.S. Scheduled Airlines (Domestic & International), February 2011-January 2012

See Tables 2, 8 and 14 of Air Traffic Press Releases for previous year numbers. Additional traffic numbers can be found on the BTS website in the Airlines and Airports box. Click on a link in the column on the right.

LOAD FACTOR AND CAPACITY

January continued the trend of 2011 when the domestic load factor was at an all-time high while the international load factor declined from the all-time high in 2010 and the system load factor equaled the previous record set in 2010 (Tables 1, 5, 9). Domestic capacity, measured by available seat-miles, decreased 0.7 percent in January 2012 compared to January 2011, while revenue passenger miles (RPMs) increased by 1.2 percent, resulting in the record domestic load factor (Table 5). The international load factor in January increased as airlines decreased capacity by 1.1 percent while RPMs declined by a smaller 0.7 percent (Table 9). Systemwide capacity was down 0.8 percent compared to a 0.6 percent increase in RPMs (Table 1). See Tables 1, 7 and 13 of Air Traffic Press Releases for previous year numbers.

TOP AIRLINES

Monthly: In January, Southwest Airlines carried more total system and domestic passengers than any other U.S. airline (Tables 3, 7). United Airlines, following its merger with Continental Airlines, carried the most international passengers (Table 11). The top 10 US airlines carried 79.7 percent of systemwide passengers, an increase from the 71.9 percent in January 2011.

United and Continental now report jointly as United.  Numbers reported as United in this release for previous years do not include Continentals numbers.  See the notes for system, domestic and international airline ranking tables 3, 7 and 11 for 2011 passenger numbers previously reported for America West.

ExpressJet Airlines and Atlantic Southeast Airlines now report jointly as ExpressJet.  Numbers reported as ExpressJet in this release for previous years do not include Atlantic Southeasts numbers.  See the notes for system, domestic and international airline ranking tables 3, 7 and 11 for 2011 passenger numbers previously reported for Atlantic Southeast.

TOP AIRPORTS

Monthly: In January, more total system and domestic passengers boarded planes at Atlanta Hartsfield-Jackson International than at any other U.S. airport (Tables 4, 8); and more international passengers boarded U.S. carriers at Miami than at any other U.S. airport (Table 12).
