Mexican Customs - MEX & ZIH

I think a key consideration is the events, and the treatment of travellers, can be wildly airport- or situation-dependent. After reading horror stories about Frontier, my trip from Mexico to California was not that horrible. In other cases with Frontier, on youtube, I saw grown men and women in tears over getting nickel and dimed by this airline, or told they would not be on the flight just for complaining. I have had interactions with TSA that were pleasant and professional or ones where they groped my crotch 3 times and I wanted to slap their faces. So yeah, we expect consistent or predictable treatment but it really depends on who is working that day and what airport you are travelling through.
