Sky Harbor Airport is very large and has an ample amount of food choices, shopping and seating.
We were very easily able to navigate thru security and to a lunch place before getting on our plane to head home. The most confusing part of the process was checking in to get a boarding pass and checking luggage. I'm not sure why this seemed so chaotic but I think that Southwest Airlines should probably look into the procedure here.
Other than that, we found a good place to eat lunch and watch the remainder of the Chiefs/Chargers game.
