Despite flying through LAX frequently (but mostly on UA) I didn't realize that these connecting tunnels were still open. I thought they were closed when they connected the satellites to the landside terminal via extended above ground concourses, rendering the underground walkway redundant. For instance at the United terminals the escalator pit has been decked over, with no trace that the entrance to the underground walkways ever existed. Nonetheless, I think it is a bad idea to eliminate this convenience, especially now that all LAX security is now under the aegis of one agency. Kenneth Lin
