OAX - LAX

It would be nice to have more room. The people next to me were tall and were literally crushed. Not fat people tall. It was absolutely disheartening to watch them struggle with the pain. I felt personally like I was in a straight jacket and confined and I am (thankfully) a very petite woman. The food choices that are supposed to be for sale weren't actually available. On both legs!!! So so sorry uncomfortable. Not the flights fault, but also there was a 2 year old little girl who screamed. Not cried. Screamed the entire flight as her parents tried unsuccessfully to console her.
