Well, first of all, be happy that your layover is now, well after the new terminals have been built, because I once spent 6 hours at the old MDW
due to a weather delay, and that was just no fun. There is minimal shopping, mainly around the "center core" right after security. Also located there are numerous eateries and a couple of bars. Unfortunately, none of the bars have views of any a/c. Not much spotting anyway, unless seeing 100s of WN
planes excites you. Long story short, get yourself a good book, sit down and have a pint or two and watch out for the Airline cameras if you don't want to be on TV
United 717 heavy, you're facing the wrong way. Any chance you can powerback to get off of my deice pad?
