Has anyone had any problems bringing their Lowepro Slingshot 200AW as a personal item? Continental allows a personal item plus carry-on. I will be bringing a luggage as the carry-on but the Slingshot as a personal item. I hate checking in bags. I've read posts here that no one has had issues with the Slingshot being a carry-on but not too sure about using it as a personal. Also, anyone know is this bag fits under the seat? Thanks.
