Los Angeles International Airport (LAX) has been ranked second among the nation’s 15 busiest airports in regards to the fewest delays experienced by its passengers on domestic arriving and departing flights, according to statistics released by the United States Department of Transportation (DOT).

On-time performance by LAX’s 15 domestic carriers was the best 12-month period since 2004, airport officials note. Between July 2008 and June 2009, domestic departures were on schedule 84 percent of the time, while 82 percent of LAX flights made a timely arrival, statistics show.

Such on-time performance placed LAX behind only Detroit Metropolitan-Wayne County Airport among the nation’s busiest airports, with LAX ranking seventh among all U.S. passenger airports for departures and eighth in arrival performance.

The DOT defines a flight delay as one that occurs when a flight either arrives or departs 15 or more minutes after its scheduled time.

In 2008, LAX served 59.8 million passengers, making it the nation’s third busiest airport and sixth busiest in the world. Detroit, with 35.1 million passengers, holds the rank of 13th in the nation.
