Ive put 12 bombers in one suitcase before. I bought those giant ziplock bags and bubble wrap. My wife said it looked like an episode of Dexter because I had all this plastic and tape/scissors spread out over the hotel room when I was packing it up.
Absolutely! Iíve done it many times. On top of what others have suggested, I say make sure theyíre wrapped in some plastic bags (yes, plural) so if they break you donít end up with beery clothes, then wrap them in a shirt or something and pack them tightly amongst other soft clothes. You should be fine.
