There are a lot of things I love about mccarran and terminal 3 is one of them. The newest terminal. Has good food choices but my go to is always Burger King for the quick snacks.
Fast security lines and nice staff. Way better then LaX ugh.
When you're getting to the TSA agent who checks the boarding pass and ID, please fill the lanes. Usually there are 2 lines on each side. The sheeple (people are sheep get it?) always back one line up. So annoying.
