I should give 4 stars, but the free WiFi is non existent in concourse. D And I really needed to get work done. They announced a walking track. How cool is that. But not sure how you can do that since you probably have your luggage.
I asked directions or questions two times and all.were helpful
Seemed like a nice airport with plugs at gates for the business or personal traveler who were low, and good restaurants with airport prices.
I can only speak to concourse.C And D. Also you have to walk just a little to get from 1 concourse to the next, but just a few walkways away, so not so huge.
