what to expect. You can only bring a personal bag for free. Carryon was about $50 more each way. The personal bag is about the size of a gym bag, it just has to be able to be shoved into a box that size and removed. They didn't check anybody's size from what we saw. There are no snack and no drinks, so just bring a bag of them yourselves. We paid a small amount each way to pick our seats beforehand, so I don't know what type of system they use to determine where everyone sits if you don't do that. Seats were more padded than Frontier Airlines. I'm 6' and didn't feel any more cramped than usual. Not luxurious, but not claustrophobic.
