This to me is a very efficient airport. I have never had major issues navigating this place and it offers slots, food and drinks in all the terminals. The security line has always moved quickly and finding flight information couldn't be easier.  The lady next to me at my gate was using free wi-fi and overall it is a clean airport. My only complaint is the taxi line can get very long when arriving and people with physical challenges end up walking quite a bit while carrying their luggage.
