Good, well organized airport, with a nice range of niche shops to beguile the traveller with time between flights.

I was pleasantly surprised to discover that Milwaukee has one of the nation's great airports, with some nice surprises in store for travelers. For example, it has a very good store for used books -- who would have thought? The airport apparently attracts some business from people who are not even traveling, because there are some unique stores, not at all mall-like.
