I have been flying in and out of Las Vegas since middle school. They have always had the best rates compared to other airlines. Our recent trip to Nashville cost us $200/per person. Other airlines were charging at least $300. There is no assigned seating, so make sure you check in online 24 hours prior to your flight to get the best boarding group. Otherwise, you'll be stuck in the C group and forced to sit apart from your party. All of the Southwest employees are friendly and some even have a sense of humor. I've even had a few flight attendants even sing a little song while onboard. The snacks have greatly improved throughout the years and they have plenty of options to choose from. You can even get beer and mixed drinks for $5 each. Restrooms are super tiny so make sure you go at the airport before you board. Overall, I've always had a pleasant experience with Southwest and I will for sure be flying with them in the future.
