How to review an airport, huh. Well, first off this is one of the world's busiest and most poplular airports. It's also one of the the largest airports in the world. It's property is so big that parts of it are in Schiller Park, Rosemont, Chicago, & Elk Grove Village. The moving sidewalk here always amused me as does the monirail they added a few years back that takes you around between gates. Allow plenty of time before your flight departs and expect delays, but the delays are nothing like in N.Y. City.
