In the packing cubes thread, loves2travel2 mentioned bringing 2 outfits in his/her carryon. In the past, I've brought a small backpack with my toilet kit, laptop and a few odds and ends, but there's no room for a day or two of clothes. Given my recent Air Canada to Egypt fiasco, I'm reconsidering carry-ons.
So what do you bring as a carry-on? Specifically, what are its dimensions?
