Airport transportation is a very important service. However, not many offer competitive airport transportation services. Some offer very expensive services and some others provide lacklustre services. Airport transportation services in USA aren't very consistent. I have seen many people prefer public transportation to special airport transportation services for many reasons. Nowadays, shuttle services seem to be doing good.

So those people in America, you may want to try out shuttle services instead of the expensive limo services when it comes to airport transportation.
