We take it on the plane with us at it fits in the overhead and both of our boys don't mind the enclosed feeling of the cot. The only thing I do not like about this is that you cannot put a cover on the mattress as it installs into a pocket on the bottom of the cot so the baby is sleeping directly on the material that is NOISY. Otherwise I would have given it five stars. We often fold up a blanket and put it at the bottom and that would be a major no no if you are using this with a very young child.
