The carpet is a little worn, but it's always clean. The outside pull-up parking is organized chaos. I haven't run into any broken machines for check-in, but they could stand a Lysol wipe. I have never witnessed a good smelling bathroom here, but every time I've gone in there is someone cleaning. The TSA line moves quickly, even though it's long. The employees there are cheerful, even though I'm sure they're supposed to be stern. (I'm glad they're friendly though.) The tram transport is efficient, especially when both are working.
I get nervous flying. Actually the airport is the last place I'd want to be. You'll probably think I'm joking, but this airport has great sushi. It's the little thing I look forward to while waiting for my flight. Actually there are quite a few great eateries. Besides the slot machines (which I never use) there is an aviation museum onsite. That's really cool and gives some great educational aspects to Vegas for those arriving from all over the world. The free WiFi makes me happy too. Overall this is a very good airport.
