The best advice I can give you is to ship it via Fedex to the destination, which pretty much will insure it will arrive on time and in tact. You can ship it in the box it came in, or construct one that is crush-proof to be on the safe side.
If you ship it on the plane, there's a good chance it will not arrive at all, let alone on time.
Good Luck,
Gary
