Can't say much about the facilities but TSA staff were nicer than other airports within the U.S I've been to and security lines moved fast. I love how there are slot machines inside the airport to make the airport seem "Vegas-esque" lol I also like the fact that the airport is really close to the Vegas strip so getting to and from is a breeze.
Downside during my visit to the airport was the mentally in-competitive American Airlines "sista" employee with an attitude that kept messing up my check-in and told me to remove some things from my not-so-heavy luggage and I was flying FIRST CLASS and she didn't even notice!! She even kept saying "so you're flying out to New York...so JFK right!? Clearly my ticket said LGA or LaGuardia and I don't if she was trying to be funny but I was pissed because it was 4 a.m the morning and I DO NOT want to be bothered!!! Ugh~ other than that, with the airport I had NO problem!!
