Very poor signage for such a big and cumbersome airport to navigate. TSA Pre lines are 50 yards from regular lines (?) Except for some (not all) TSA employees, everyone treats you as if they are forced to, from several SouthWest employees (I am an A-List) to others around. If they can't handle the public, they need to find themselves another job. I travel to 200 clinics in 21 states. I have yet to find an airport in the US that is this bad in service. Only good thing is you have plenty of food choices.
