I've had no problems flying between DTW and SEA. I bring beer from Michigan to share with friends, which also serves as reminder to not over pack on the return flight and cause the baggage fees to rise. In addition to clothes as padding, koozies serve as an additional safety measure. As long as you don't have bottles knocking each other you should be good. If you hear that clinking sound, repack. Cans of any kind are bad news. Aluminum cans fold and wrinkle when not in a packaging carrier which creates a small pinhole leak.
