Here's the thing, Phil. I appreciate your input, but I don't check bags, I don't rent cars, the only airline that really has a line, ever, is Southwest, and when I park at the Parking Spot, it takes me about ten minutes to get to my gate, and I have free parking points until Kingdom Come.
I don't eat when I get past the gate because I show up about 15 minutes before my flight takes off. I take a leak before I go through security.
When I deplane, it takes me two minutes, tops, to get to the area for the Spot bus to pick me up.
I've been to dozens of airports, ranging from local and regional to international, and MCI is the most user friendly for the local traveler.
