If you are driving from Canada to Buffalo NY, you only need a drivers license (government issued i.d.) to cross the border from CAnada to the USA. But you do need a passport to fly. Even though it's a domestic flight within the USA, unless you hold American citizenship, you are are, to them, a foreign citizen on a domestic flight. I would recommend a passport.
