thanks for the advice guys! i think i may just buy a ticket for it (no customer service reps are saying a 'yes' to guitar carry-ons). i'm moving there so i've got a lot of stuff..plus my guitar is a custom martin (yeah i'm no django..was given to me as heirloom type gift from my uncle..my thought was why have it just sitting in a closet at my moms house..but now regretting it). i was given specific instructions not to check it..i assume les pauls and other electrics are much more durable and can withstand the temperature extremes a lot better. i'm afraid the temperatures under the cabin will warp the precision craftsmanship. plus i don't have the lock for the case..extra worry. was thinking non-air mail because of the temperature extremes. well, if you guys have any other pieces of advice, i'd appreciate it!
