There are two kinds of bags:

Carry-on and Lost.

I only check bags if there's really no other option - and yes, that means I travel without a knife. Well sort of. More on that later.

I have tried every permutation of bag there is and I've come to the conclusion that the best way to carry a suit is to wear it onto the plane. Put your "not work" clothes in the bag. Arrive dressed for work.

Forget trifolds and all that. Just wear it. Steam it in your hotel when you get there and wear the same suit every day - that's what they are for.

As far as the carry-on bags, I am never buying a roll-aboard again, because I bought the last piece of roll-on luggage I'll ever need:

It was $340. Outrageous? All you need to do is have 3 cheaper bags fail over your lifetime and you'll spend more.

I also have a soft leather shoulder briefcase, it's perfect. My wife got it for me. With those two, I can go anywhere, for an indefinite period of time (just do some laundry now and then).

Oh and the knife? I have a very well-travelled item that I found in home depot that does everything a knife does. But it's not a knife. And I put it in plain sight at the TSA checkpoints. Over and over and over again. That's all I'm sayin' here.
