The Minneapolis-St. Paul Airport is a great place for the traveler on a layover. Although most of my traveling through this airport have been during layovers, you can tell that this airport is efficient. There are quite a few retail stores for browsing while on layover and plenty of coffee shops and food booths. Because the terminals are quite long, there are both trams that connect the gates and an underground moving walkway that connects the terminals. Overall, a great airport that makes air travel pleasant and comfortable.
