The number of passengers traveling through Los Angeles International Airport continued to climb last month, according to figures released Tuesday by Los Angeles World Airports.

Nearly 6.8 million passengers traveled through LAX in June, up 4 percent from 6.5 million in the same month last year. International travelers led the way, with the number of international passengers flying in and out of LAX growing nearly 7 percent compared to June 2014. The number of domestic travelers, who account for the bulk of LAX traffic, grew by just shy of 3 percent.

Through the first six months of the year, LAX has seen 4 percent more passengers than in the same time period last year, keeping the airport on pace to break its record for total passengers, which was set last year.

The volume of air cargo passing through LAX was also up in June. During the month, 172,486 tons of cargo moved through the airport, an increase of 3.4 percent compared to the same month last year.

The volume of air cargo is up 11 percent through the first six months of the year, compared to the same period a year ago, likely thanks to labor disruptions at local seaports. Slowdowns in San Pedro and Long Beach earlier this year pushed some importers and exporters who would normally use ocean freight to fly cargo into Los Angeles instead.
