I love flying SW. This location is terrific because there are plenty of places to eat in this terminal and if you're bored, many slot machines to use and shops to browse through while you wait.
The staff of Southwest all have this snarky (in a good way) attitude that adds humor to your travels. I love coming through Las Vegas and flying Southwest Airlines because overall, the customer service is great, no assigned seating and there's never any hassle. Highly recommend! :)
