The passenger volume at Los Angeles International Airport (LAX) last year jumped 4.7 percent from the previous year to nearly 61.9 million passengers, airport officials said.

The domestic passenger volume rose 4.6 percent from 2010 to approximately 45.1 million passengers, while international traffic grew by 4.9 percent to about 16.7 million passengers from 15.9 million in 2010, airport statistics show.

However, total air cargo tonnage at LAX dropped 3.8 percent last year to about 1.9 million from 1.93 million in 2010. Air mail tonnage rose 8.6 percent to 80,442 tons, while freight tonnage decreased 4.2 percent to 1.8 million tons.

The airport also saw a 4.8 percent increase in the number of landings and takeoffs to 603,912 in 2011 from 575,835 in 2010.

“The increased passenger activity at LAX is attributable to several things: new international service; an improving Asian economy; and a modest, but perceptible strengthening of the Southern California economy,” said Gina Marie Lindsey, executive director of Los Angeles World Airports, the city department that owns and operates LAX.

“While LAX has not come close to seeing its pre-9/11 traffic of 67 million passengers, the 2010 activity demonstrates a stronger travel demand than we’ve seen in several years. The drop in cargo activity is somewhat puzzling. We need to dissect the numbers and understand underlying causes.”
