If you're flying Alaska this terminal is awesome since it's quiet and not hectic unlike the main Mc Carran facility. Usually the TSA lines move fast and quickly here. The only issue is that this terminal is removed from the main Mc Carran facility and one time we arrived on Southwest and was connecting on Alaska so it was confusing and took over an hour to get from the main terminal over to terminal 3 via a shuttle. I can imagine others getting lost if they had our dame ordeal. Otherwise if you're only using Terminal 3 it's quick and easy.
