I bought a carry-on a year ago with a handle and wheels and thought it would do the job. Was I wrong! While in the Dallas airport(one of the world's busiest) last weekend, the height of the handle wasn't as useful as I had hoped. The carry-on toppled over twice while trying to make it to my gate destination.
It just so happened I saw an article in the June edition of Consumer Digest while at a bookstore yesterday. If any Ziners have had any frustrations with their carry-ons, this article may be of some help. I'm ordering a Victorinox Swisswerks(a 22 inch one).
