From Implicit Simplicity: Pack like a carry-on traveler (tight and light) but check for ease and retain the carry-on option…
My solution is to have a small carryon-sized bag small enough to bring on the plane if that would be the best choice and sturdy enough to be checked in. This means I can effectively trust my bag to the airline instead of carrying it through the airport and worry about it at every turn. I know some people won’t agree with me here, but strangely enough, I find that I am more at peace when I don’t have to be responsible for my bag. Besides, I never pack anything in there that cannot be replaced. That would be stupid. If my bag should be misrouted or stolen or whatever I can use the BIT method of travel as described by Tim Ferriss.
Note that the key to my method is to have a choice, not to haul a lot of stuff. My bag need to be sturdy enough to survive the not so gentle treatment of airline personel
