Los Angeles International Airport (LAX) served more than 59 million passengers last year, a passenger volume increase of 4.5 percent from the previous year, airport officials said.

The airport experienced a 4.1 percent growth in total 2010 domestic volume to approximately 43.1 million passengers from about 41.4 million in 2009, according to statistics. International traffic at LAX grew by 5.5 percent last year to approximately 15.9 million passengers from 15.1 million in 2009.

Airport officials noted that total air cargo tonnage also increased 15.8 percent to 1.93 million from 1.66 million in 2009, while air mail tonnage rose 15.5 percent to 74,034 tons from 64,073 tons in 2009. The amount of freight served at the airport increased 15.8 percent to 1.85 million tons from approximately 1.6 million tons in 2009.

The number of aircraft operations, which includes both landings and takeoffs, increased 5.6 percent to 575,835 in 2010 from 544,833 in 2009.

Airport officials attributed the increases to economic improvements and expanded airline routes.

“LAX is experiencing increased passenger and cargo volumes due to continued improvement in the global economy, further assisted by added service on existing routes from several domestic and international airlines, as well as by new airlines to new destinations, including Alitalia to Rome and All Nippon Airways to Tokyo-Haneda,” said Gina Marie Lindsey, executive director of Los Angeles World Airports, the city agency that owns and operates LAX.

“Our statistics show that upward movement in traffic continues to be the norm.”

LAX is the seventh busiest airport in the world, offering more than 565 daily flights to 81 destinations in the U.S. and over 1,000 weekly nonstop flights to 66 international destinations on nearly 65 passenger and 20 all-cargo airlines.
