I was looking at a replacement bag that I could slip over my Samsonite spinner and wheel both bags at once UPRIGHT, not piggyback, like I did before.

This bag fit perfectly, and now I have the option of piggyback or upright.

This bag is compact for carrying a 17" laptop with accessories, iPad, notebook and other essentials and fits under the seat in front of me (assuming I don't get upgraded) with room to spare for my legs....yay!

I have bought TUMIs in the past, but decided they were nice but not worth the price.  This bag is well constructed, roomy enough for me (really, this is such a personal decision for us road warriors, I know), and I can buy 7 of these for the price of a TUMI.

My only wish is that is was wheeled......BUT, it would naturally weigh a lot more.....all in all this bag does the trick for a nearly 3,000,000 American Airlines miler (all miles, btw, no stuffers, and you AAers will know what I mean).  Best travels to you all!
