(No one here would want "oversized." We're all looking for the smallest, lightest, most convenient bag we can buy that can still carry what we need to bring on our trip.)
Good luck !!
Ditto.
Now, to the OP...
Organization on the inside of the bag is the least of the problems that I myself, and a huge number of FF's that I have met are concerned about. Almost all of us have developed a system that works for us.
I did fill out your survey.
To this very day, NO ONE has, in my opinion, created what I would consider an even close to perfect carry-on. Carry-on is the real market, IF you are targeting fliers.
I had an idea about a carry-on that I think would work great, but I have neither the time nor the inclination to start a travel company. If anyone ever sees this, feel free to give me 5% of your net if you try it and it works :P
1. A semi-rigid carry-on that flexes very little and retains its shape. I'm thinking very similar to TravelPro bags, except more rigid in not "plumping up" in the middle when overfilled.
2. Don't put any pockets on the inside or outside. A smooth, perfect shell (as it can possibly be), both inside and out. FF's will use their own bags as pockets IF they need them (there are plenty of these available on the internet). You could also sell "drop in" pockets that fit your bag perfectly.
3. No handles on the outside. Just a pull-up towing handle that has a locking position just one inch above the bag (operates as lifting handle). The towing handle would take up a little space inside the bag (a la TravelPro), but that would be the only thing to do so. When that handle is locked down, the outside of the bag is a perfectly smooth shape on all 6 sides (except for about a 1/4 inch protrusion on 2 sides for outboard inline-skate wheels, a la TravelPro).
4. The bag is specifically made to fit, with a minimum of clearance, an overhead bin of a specific aircraft.
5. The bag would have 2 identical "stripes" over the base color, circumnavigating the girth around 2 different axes. Visible from all sides. The stripes would be boldly imprinted all around with the words CRJ, B737, etc. (as the bag was designed for) Eliminates the need for identifying strap. Also, I had a strap made once that said "CRJ 900" on it, after repeatedly being told that I had to gate-check the bag. After that -- Carry-on worked like a champ, No Worries.
Bag that always fits snugly in the bin, minimum hassle, maximum capacity.
