Phoenix's sky train connects to the east economy parking lot, before continuing to the light rail. Wikipedia says it's being extended to the rental car center on the west side of the airport. When this is finished, they won't need to run busses anymore. It's perfectly useful, especially for people who park at the airport's economy lot. But the graph on this page makes Phoenix's train seem useless. https://en.wikipedia.org/wiki/PHX_Sky_Train https://en.wikipedia.org/wiki/PHX_Sky_Train (When Terminal 4 was designed/built in the late-80's, they left space for a people-mover-tunnel. When they came back 20 years later to build the people-mover, they realized there wasn't enough space for the tunnel. They built an elevated people mover instead. This is/was the only/first airport train to go over an active taxiway.)
