Should a travel with a (huge) backpack or suitcase to a grad school interview? Does it matter?

I'm hoping my backpack will fit as a carry-on (during flight), and would be convenient for a 3-day trip.

Carry on bags have to fit into certain physical dimensions and weight limits. Otherwise you'll need to check them. Also, there're restrictions on what you can carry in a carry-on bag for security reasons so beware.

Check with your airline well before the day of the flight so you'll know for sure.

I would take a small luggage bag, and a medium backpak...that always work...good luck w/ ur interview

I'd go with the suitcase--it looks less like a college undergrad, and more like a serious adult. Also, carry on your essentials, in case your luggage gets lost
