Being much more familiar with LAX, I found the process of going from Terminal 1 to Terminal 3 very confusing as I got two different answers when I asked the Southwest skycap and someone at the Information Booth inside T-1. What prompted two stars was the way that the TSA treated my friend (who was traveling back to her hometown from T-3) when she forgot that she had a bottle of water at the bottom of her backpack (she had gone hiking at Zion and Bryce Canyon before we met up in LAS). You'd think she was carrying a bomb, for goodness sakes! She was so upset at their reaction to this honest mistake. I told the TSA staff in T-1 about it and they agreed that it was an inappropriate response.
