Airline Information Airline Traffic Annual Release: 2001

Fewer airline passengers traveled on U.S. airlines in 2001 than in 2000, the first annual decline in a decade, according to the year-end report on aviation traffic from the U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS). 


The number of passengers had increased every year since 1991.  The number of U.S airline flights, which also declined last year, had grown every year since 1997. The decline in traffic was caused by the events of Sept. 11.  Through August, enplanements were up very slightly, but for the remaining four months there were 20 percent fewer passengers than in 2000. 


In 2001, 622 million passengers boarded 8.8 million U.S. airline flights, down from 666 million passengers on 9 million flights in 2000. 


While passenger enplanements were down 6.6 percent and flights were down 2.7 percent from 2000, freight revenue ton-miles were off more than 7 per cent.  International freight was down 7.8 percent. 


The major airlines—those with annual operating revenues of $1 billion or more— reported an overall decline in passengers of 7.4 percent during 2001. American Trans Air reported the biggest increase, almost 10 percent, while only two other major airlines, Southwest Airlines and Alaska Airlines, reported a rise in passengers. The biggest drops were reported by United Airlines and Delta Air Lines, both of which carried 10 percent fewer passengers in 2001 than in 2000.
