This might be an answer to those who either can’t or don’t want to put their carry-on’s in the over head bin above their airline seat. It looks like it would be a good option for your laptop as well but you might still want to ensure it is in some sort of sleeve for additional protection. This carry-on has a telescoping handle, multiple side pockets, and a large interior. It’s boon though is it’s ability to sit under the front of your seat with a design that allows easy access to the contents contained within. Personally I value every inch of cramped space airlines feel they can bestow upon me but if you can live without the toe space this will take up than it’s great choice for you. Costs about $119US.
