Airline on-time performance improves, more than 1 out of 5 late

Continued route and seat cutbacks have led to yet another month of improved airline performance this year. For July, the 19 largest airlines in the United States reported an on-time arrival rate of 77.6 percent. This is higher than July 2008's 75.7 percent and June 2009's 76.1 percent, according to data from the U.S. Department of Transportation's Bureau of Transportation Statistics. But, it still means that more than 20 percent of flights did not arrive on time. That's more than one out of five.

The decline in traffic has led to improved performance. In July this year, only 580,000 flights were scheduled – down 8 percent from last year's 628,000. Close to 40 percent of delays were caused by weather.

You have the best odds of an on-time arrival with Alaska Airlines, which turned in an on-time rate of 87.2 percent. AirTran was at the bottom, with 69.7 percent.

Almost 7,000 flights were canceled in July (1.2 percent of the total), with 164 flights stuck on the tarmac for three hours or more (29 for four hours or more). Thirty-four US Airways flights spent more than three hours on the tarmac, making it the leading transgressor, followed by Delta with 26 and JetBlue with 24.
