When flying United I often have a layover in Denver or Chicago. I would choose Denver over Chicago any day of the week. Yes, the airport is a ways out from the city of Denver but the airport has everything you need for a 2 hour layover. Good choice of restaurants, lots of computer access and even a few places where you can stop and get a massage. I've often experience delayed flights and I'd much rather be stuck in the Denver airport than Chicago, LA or any other large city airport.
Pros: Restaurants, Bars, Computer Access
Cons: Location
