My first trip in new terminal last week. A+
My lawd in heaven, some of these people.
Ridiculously long walk . . . 
There are a lot of people who need to learn to deal with the airport, 90% of all airports are like KCI now and they don't know how to deal with pick ups, moving sidewalks, etc.
My experience is honestly B+, it's nice, and overall a massive improvement, but they seemed to cheap out in some areas, and they definitely need to go through with a punch list crew and fix a few things, loose taps, TP holders that aren't properly mounted (mine was swinging from once of it's non receded screws), both of those happened just using the restroom once and that's insane (though minor) misses on something that should have been "done"
Maintenance wise they gotta step up too, early flight out yesterday, took 3 soap dispensers before I found one with soap, scuffed floors (really noticed it coming in late night Wednesday, better yesterday morning but still noticeable), and again, bathrooms looked in general as well kept as the old ones. Can you tell i was not impressed with the bathroom upkeep.
It's a bit nitpicky I get it, but for something that is 3 weeks old it is treated like the old one which is poor at best.
