Interesting design, shows some thought went into it. May fit under the seat ahead of me if I get the window seat, but will definitely fir in an overhead bin. Like the handles on both ends and the E-Z stow backpack straps for versitility. Zip-up internal dividers can be handy in a dirty duds vs. clean duds deploy relo. Only improvement might be two more zipper heads on main run to allow easier access to end compartment(s) in under seat application.
