People watching – everybody does it. We even stopped a few travelers at Stuttgart Airport to ask: What’s your favorite carry-on bag?

MOTAR KAMARA, social worker
My little case is very practical - it's really small , quick and easy to stow and doesn't take up an entire overhead locker.

JUANJO HINOJOSA, choreographer
I like using a backpack because I travel a lot and have to be able to locate my stuff quickly. That's what's so great about it.

AMINATA FAUSTMANN, U.N. employee
No question: my purse. I keep all my important stuff in it. It has emotional value for me, too.

LYNN XU, marketing manager
I like to travel light and take a backpack so my hands are free. Plus, a backpack fits snugly into the space under the airplane seat.

CHRISTA ERDLEN, doctor's receptionist
I've got my handbag with me because the most important thing I take on a trip fits inside it: the book I am currently reading!

NATALIE PAHNKE, student
When I'm off to places I don't know, I prefer to take a bag that's easy to carry rather than a wheeled case that rattles over cobblestones.
