Ok, not needed for this one, but someone might find this helpful...
Check the airline's baggage policies, you might be able to check it as a "special" item, although that could incur a charge too. I was checking about checked baggage for our recent trip to San Francisco, since we were going to a wedding I knew we couldn't get it all in carry-on, and saw some mention of "special" baggage-- I think the examples were Guitars, skis, car seats. Maybe they'd handle it nicer, especially if you stuck "fragile" stickers all over!
