I used whole salmon shipping boxes to bring my meat back on Continental airlines. These boxes are made out of styrofoam and weigh practically nothing. I got some large cardboard boxes that I cut to fit tight around the styro for extra protection. You can tape 3 together and UPS them out before you go. They are so light shipping is almost nothing to get them out there. I got these boxes from a local fish supplier that supplies nicer restaurants with tuna,salmon, lobsters and such. They just throw them away. I had all my clothes in my carry-on, and camera case(large fanny pack) clipped around waist. One box had 96 lbs. of meat, another had 89 lbs. and the third had 70 lbs(cape and meat together).
Break down:
Carry on and camera case-Free
Gun case-----------------Free
Box with 96 lbs.-----------Free + $50.00 overweight charge.
Box with 70 lbs.-----------$80.00 for extra+ $25.00 over 50 lbs.under 70
Box wtih 89 lbs.-----------$80.00 for extra bag + $50.00 over 70 lbs.
Antlers 300 inch 6x6 whole was to be $80.00, but she said I was paying enough and didn't charge me for them.
I paid $285.00 for everything.
