The line at TSA took me 2.5-3 hours to get through and I was behind on my flight time by 20 minutes. I was told some flights would be delayed and they would wait but when I arrived the flight had already taken off. I showed up on time and even then 2 and a half hours was not enough time to make my flight. I had to rent a car and drive from Vegas to San Diego at 8:00pm. I just hoped the airport would have notified their passengers a lot better.
