It is estimated that Los Angeles International Airport is the world's fifth busiest airport. LAX served some 60 million passengers and more than 2 million tons of freight in 2004. It is the third busiest airport in the United States and second busiest international gateway, behind only JFK International Airport in New York City according to the U.S. Bureau of Transportation Statistics. In 2005 more than 61 million people traveled through LAX. A commerce leader, its ever-expanding air cargo system handled more than 2.1 million tons of goods. International freight is more than 50 percent of this total. Convenient location, modern facilities, and superior sea/air/land connections have led to LAX's designation as a world-class airport.LAX provides many services to assist passengers or visitors with disability. Along with special parking spaces, rampways and elevators, a free shuttle equipped with a lift for disabled persons in wheelchairs operates between Lot C and airline terminals. Telecommunications Devices for the Deaf (TDD) or speech-impaired are available in all terminals.
