I'm writing this in the airport.

So far I'm really thrilled with this luggage. The different organizational options are terrific. Getting to the airport was a breeze with the two (main bag and daypack) attached together. When I got to the gate, I unzipped the daypack (with the iPad I'm writing this on, a book, cell phone, adapters, ear plugs, eye mask, lip balm, and plenty of room for more stuff) and slid it onto the retractable handle.

The handle does wobble a little, but I seem to remember that was also the situation with my last carry-on (which I never used because I started carrying a laptop backpack). Incidentally I did test the daypack at home with the laptop and it was fine, although obviously heavier.

Anyway, on the plane the main bag had no trouble going into the overhead of a smaller US Airways plane, and the daypack went under the seat in front of me with plenty of room (esp. versus my bulkier laptop backpack, which is still great for other situations).

Also wanted to mention the daypack has pockets in all the perfect places: for example, a tiny pocket where I put my ID and boarding passes, and another pocket for adapters within easy reach. And then another pocket for keys, the lip balm, tissues, sunglasses, eyeglasses, etc.: really a lot of room for more.

The best part is the main bag has room for my pajamas, 4 pairs of socks and underwear, all toiletries, a couple of shirts, and a couple more books. This has been my first attempt traveling with enough stuff for a week in a carry-on, and this made it happen effortlessly.

And if I ever went someplace where I needed take trains, like India, the whole thing could convert to a giant backpack!

(Take that, Rick Steves, whose similar but smaller designed bag I was initially considering.)

As you can tell, really love this bag!

===== UPDATE =====

Successfully "lived" out of this for one week! On the way home, on a smaller plane, they were making people with carry-ons check them. I just zipped off the daypack and strolled on through, no hassle! Yay! Love, LOVE this bag!
