James, 47, has passed through this airport several times before, and feels sorry for foreign visitors."I'm still lost, and I'm an American," he tells AFP. "This is really annoying."The infuriating design of LAX -- the main airport in America's second biggest city -- is almost legendary.About 95,000 vehicles pass through the airport daily, most of which funnel into a bottleneck: a horseshoe-shaped roadway looping past all the terminals, where every passenger tries to get dropped off or picked up as close to the entrance as possible.
