This new generation of rolling carry-ons and rolling suitcases is the berries. What a back-saver. Find the lightest, most durable stuff you can find. I like the ThinkPad Vertical Roller Case (model #40Y7384) but that’s probably just because I’m a Thinkpad guy. Still, they’ve thought of everything on this briefcase: gel padding, vertical “upright” design, telescoping single handle, has a retractable document holder built into the top (perfect for tickets, passport, directions), removable water bottle holder, removable cell phone holder, ultra-nice ID tag holder, business card storage, fits in all overhead luggage bins (including the thin Canadair “jump jet” bins), … I mean… they even give you a retractable *blue* LED flashlight inside! Yes it’s $132. I know. Too much. But mine has lasted for 20 years I think. Ok… maybe not quite that long. :-) Keep the rolling suitcase to a manageable size (not one of those rolling *trunks*!) and you can easily glide them both behind you, one in each hand.
