I get a lot of questions about my travel bag. Being a frequently traveller (somewhere different every week), I got tired of carrying two (2) bags onto the plane.
The rules in the airlines are, put one (1) in the overhead and the other under your seat. Well, then you have the crappy old American Airlines MD-80 configurations where the A-B side of the plane has smaller overheads than the D-E-F side. So you cannot stick MOST roller-bags wheels first on that side (only sideways). See:
These planes ALWAYS run out of overhead space once they get to about 75% capacity. 
Being Executive Platinum, I usually get to board before this happens. But sometimes, I get stand-by on an earlier flight or end up running late and get on the plane and its already packed. And sometimes 
, I fly a different airline and don’t get priority seating. 
So, I needed something that could carry at least a weeks worth of clothes, my laptop and extra equipment. But it also had to be small enough to fit on the A-B side of the plane (and even under the seat). So I looked and looked and found the Samsonite X-Space Spinner:
I love this bag. 
Here are the features:
- Multi-directional wheels allow 360 degree upright rolling in multiple directions with no weight on your arm.
- Large main opening provides easy access to contents
- Shock absorbing padded computer compartment accommodates up to a 15.4 laptop
- Removable organizer keeps smaller items securely contained
- Multiple organization compartments provide storage for small items and other incidentals.
- Upright locking handle for easy maneuverability
- Top carry handle
- Size 17.0000 x 14.0000 x 7.5000
- Linear Inches 38.5000
- Warranty 10 Years
Now, I did have to get used to packing lighter and more efficiently. For example, I no longer carry a large 3 head shaver. I got the Norelco HQ40:
But with this bag, I am usually able to get 5 days worth of clothes, a pair of gym clothes, my laptop, power cord, a few USB cables, my GPS, toiletries and… uh… my iPad. Yes, I know who I work for…
I have found ways to fold my clothes (or not fold, as in socks) to get everything into the bag. It is amazing what you can fit into this bag.
Efficiency is the name of the game.
