BTS Releases September 2007 Airline Traffic Data;  
Nine-Month 2007 System Traffic Up 3.6 Percent From 2006
 

U.S. airlines carried 582.0 million scheduled domestic and international passengers on their systems during the first nine months of 2007, 3.6 percent or 20 million more passengers than they did during the same period in 2006, 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 the combined domestic and international load factor of 80.7 percent from January through September was a record for the nine-month period (Table 1).

U.S. airlines would carry a record number of passengers in 2007 if growth from 2006 continues for the rest of the year.

U.S. airlines carried 3.5 percent more domestic passengers and 4.4 percent more international passengers during the first nine months of 2007 than during the same period in 2006 (Tables 7, 13).

In September, the most recent data month, U.S. airlines carried 59.2 million scheduled domestic and international passengers, 4.9 percent more than in September 2006 (Table 2). The number of domestic passengers increased 4.7 percent in September from a year earlier and international passengers increased 6.5 percent (Tables 7, 13).

Top Airlines
Southwest Airlines carried more total system and more domestic passengers for the first nine months than any other U.S. airline (Tables 3 and 9). American Airlines carried more international passengers than any U.S. carrier (Table 15).

Top Airports
More total system and domestic passengers boarded planes in the first nine months at Atlanta Hartsfield-Jackson International than at any other U.S. airport (Tables 5 and 11); and more international passengers boarded planes on U.S. carriers at Miami International than at any other U.S. airport (Table 17).

Flights Operated
U.S. carriers operated 8.0 million domestic and international flights in the first nine months of 2007, 0.8 percent more than were operated during the same period in 2006 (Table 1). Domestic flights increased 0.9 percent from the previous year while international flights were up 0.6 percent (Tables 7, 13).

In September, U.S. airlines operated 866,700 scheduled domestic and international flights, up 0.1 percent from the number of flights operated in September 2006 (Table 1). The number of domestic flights increased 0.2 percent in September from a year earlier while international flights decreased 0.1 percent (Tables 7, 13).

America West Airlines and US Airways reported data separately in September because the carriers held two operating certificates despite their merged business operations. They are now operating under a single certificate and will begin reporting data jointly later this year.

In other total system comparisons from the first nine months of 2006 to the first nine months of 2007 and from September 2006 to September 2007 (Table 1):
