LAX received 14% of the votes. In the words of one frequent user, it was "built for a different time" and no doubt was attractive in that time. But the number of passengers kept growing. The space required for security kept growing. The airport did not keep growing, although it now seems to be trying to catch up. LAX has nine terminals including an international terminal, which is currently undergoing a $1.5 billion expansion. Some terminals appear old and decrepit. Commented one reader, "most of LAX is like a Turkish prison." Another reader claims to have "noticed mushrooms growing out of the ceiling" in an underground airport passageway. Because it is one of the principal U.S. gateways, LAX is only becoming more important given the increasing cooperation within the three global alliances and the increasing competition between them. So improvements are badly needed.
