I have flown into Las Vegas airport several times and I have to say it looks like it keeps getting bigger all the time. The one thing I love about this airport is that it is clean and there is never a lack of being able to purchase food or look for a restroom and the service is awesome. I never have to wait long for my bags because on this last trip I literally went to the restroom and my bags came out so fast that when I went to look for them they had pulled them aside for me and had them ready.
Because this airport though is so big my one big gripe is that when you are picking someone up you have to go through the parking lot on the 2nd floor which unlike SFO of SJC or even Oakland you can pick people up right outside of the baggage claim area. This airport has 3 building which you can take a bus too and it is really cheap. They have an area just for Lyft and Uber pick up and a different location for taxi cabs. I have to say though that they are pretty well organized but again the airport is very big but there is always someone around to point you in the right direction.
Also, they have carts everywhere for convenience if you end up carrying a lot of luggage like me and if you are waiting let's just say there is no lack of entertainment because there are slot machines everywhere and in the Southwest area they have a slot machine with a smoking room. I know bad habit but I will kick it soon enough. Also, many of the shops have good prices on merchandise if you are looking to do that last minute gift shopping as you are leaving the airport. The restrooms are kept clean but they don't have the fancy toilet seat cover that Chicago has but not even fancy seat covers will ever make me go to Chicago Airport again. That is one of my do not fly zone areas. So if you are flying into Vegas get ready for the bright lights and bing noises for it is right there when you get off the plane..
