Thursday, March 15, 2007 - U.S. airlines carried 744.4 million scheduled domestic and international passengers on their systems in 2006, 0.8 percent more than they did in 2005, the U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) today reported in a release of preliminary data (Table 1).

BTS, a part of DOT's Research and Innovative Technology Administration, reported that U.S. airlines carried about the same number of domestic passengers and 6.0 percent more international passengers in 2006 than in 2005 (Tables 7, 13). These passengers traveled on planes with average load factors exceeding 79 percent (Tables 1, 7 and 13).

In December, the most recent month, U.S. airlines carried 60.7 million scheduled domestic and international passengers, 1.9 percent more than in December 2005 (Table 2). The number of domestic passengers increased 1.2 percent in December from a year earlier and international passengers increased 7.3 percent (Tables 7, 13).

Top Airlines in 2006

American Airlines carried more total system passengers in 2006 than any other airline for the fifth consecutive year (Table 3); Southwest Airlines carried more domestic passengers than any other airline for the third consecutive year (Table 9); and American Airlines carried more international passengers than any U.S. carrier for the 17th consecutive year (Table 15).

Top Airports in 2006

More total system and domestic passengers boarded planes in 2006 at Atlanta Hartsfield-Jackson International than at any other U.S. airport for the 11th consecutive year (Tables 5 and 11); more international passengers boarded planes at Miami International than at any other U.S. airport for the 12th consecutive year (Table 17).

Flights Operated

U.S. carriers operated 10.5 million domestic and international flights in 2006, 2.8 percent fewer than were operated in 2005 (Table 1). Domestic fights were down 3.3 percent from the previous year while international flights were up 3.1 percent (Tables 7, 13).

In December, U.S. airlines operated 869,700 scheduled domestic and international flights, unchanged from the number of flights operated in December 2005 (Table 1). The number of domestic flights declined 0.5 percent in December from a year earlier while international flights increased 5.3 percent (Tables 7, 13).

America West Airlines and US Airways report traffic data separately because the carriers hold two operating certificates despite the merged business operations. They will file a merged traffic report when they operate under a single certificate.
