Why is there sometimes an "X" added on the end of a three letter airport code? i.e. LAX

I thought that it might stand for international, but that doesn't make sense, because ORD (Chicago O'Hare) and many other airports are international and don't have X on the end. Anyone know? I live in PDX, and I always get asked why there's an X when I'm travelling and refer to Portland as PDX.
