I added in a paragraph with an edit that you probably didn't see, but to be clear these are separate problems. The plane trains are to get people around an airport. The subway/train connections are to get people to/from an airport. He's wrong two ways. (1) most if not all major US airports are connected to rail and (2) international airports use plane trains and if they don't they have buses that do the same thing.
