The Vegas airport is pretty damn busy but it's not as crazy as say, LAX. I've flown in and out a bunch of times now and this last time was actually the quickest trip.
We arrived and hustled to get on a tram to take us to baggage claim (from Southwest) and only waited about 10-15 minutes before the bags came in. There was no security checking if you got the right bag on the way out.
We had to pay an airport fee to get out of there via shuttle. It was over $20 to get to the strip but then about $12 to get to the airport.
Coming back to the airport, there were crazy lines everywhere. I think there should be some handbook on how to decipher what the airport workers are saying but alas, it's all in secret code.
Security was pretty lax. I forgot to take off my belt but I went through just fine.
Airport food options were plentiful though probably questionably healthy. I saw Popeye's Chicken on my way to my terminal. There were also a gazillion newspaper stands. I did appreciate the charging zone where they had a strip of power outlets for you to charge up your phone or plug in your laptop.
In general, I rather fly here than drive from LA.
