I love my Checkpoint Flyer, but there is one way this excellent bag could be improved. I have recently started using the back pocket as a 'slip over the handle' on my rollaboard. However, the bag often slides to the side, since the handle is les that 1/2 the width of the pocket, and the zipper does not work in making the pocket narrower. What I think would work well is a (heavy) velcro divider down the middle of the pocket. Of course, if you want to use the pocket as a pocket, then TB could provide a strip to place on the hook part of the velcro.

If you think this is a good, practical idea, I would love to have my bag retrofitted, perhaps even as a test case.
