We were in the last group to board and were told we HAD to check our carry on bags due to limited space, but once we boarded we saw plenty of space so that was kind of frustrating...

Staff knew my friend and I were not sitting together and they did what they could to get us next to each other! Great customer service

The super cheap economy with no carry on is more trouble than it’s worth and you need to be more clear before payment online about what the restrictions are.

I was accompanied by my mom and unfortunately she sat to a very odorous person. Which would be the only complaint I have. And we were seated apart.
