Reminds me of an old casino because of the dated interior and slot machines. Security moved with no urgency and they are somewhat rude. The Southwest terminal seemed somewhat small with limited food choices, especially for early flights. I had to catch a 7am flight to Baltimore and I had to get on the shuttle at 5 am from my hotel. I was hoping to grab breakfast from the airport. The only open restaurant I saw was Starbucks.
The only good thing was claiming baggage went quick. When this is your only option in Vegas, you can't complain too much I guess.
