I took a long weekend trip to New York City, to visit family, and while in the airports I had the opportunity to do some people-watching. I took particular note of what flyers use for carry-on luggage in order to see if I need to upgrade the rucksack I have used for some years. Although I don't need to change what I carry, I did see that many travelers are using spinner luggage -- the kind with four wheels that is very easy to maneuver, in lieu of the pair of wheels on the bottom of a drag-along.
This Samsonite LIFT 29" Expandable Spinner Luggage ($198) is typical of many spinners that I observed; the lightweight -- at 10 1/2 pounds -- and very durable bag is fully lined and with the beveled alloy pull handle and integrated top and side carry handles is a snap to move and store in a car trunk or overhead compartment. The four multi-directional caster wheels take the weight of the bag off your hand and arm while you're pulling the luggage on the sidewalk or concourse.
