When the prices are better we opt to fly into Milwaukee instead of Chicago. The airport is much smaller and thus much less chaotic. It has everything you'd need in an airport (although a pretty small food court), and even has a nice used bookstore which I think is a really good idea. The fares can be more expensive to fly into Milwaukee because it's smaller, but there are times when I've found much cheaper flights because I think the businessmen who have more money to spend would rather fly into O'Hare so they're trying to get people to fly into Milwaukee by lowering fares. So keep your eye out for that.
