I’m currently using the Jansport Right Pack as my “personal item” when I fly Frontier. Which is slightly more than expensive than the Jansport City Scout because its fabric is Cordura instead of Polyester. Both have the same dimensions which are: 18″ x 13″ x 8.5″. There is half-an-inch of extra depth than what is officially allowed by Frontier, but it has never been a problem for me. The bag has a large main compartment, which makes it ideal for stuffing as much as you can into the limited amount of space.
