Where are u going and what are u hunting for would be helpful for answer. Getting an antelope home is a lot simpler than getting a moose home.
I wouldn’t trust my bow in anything less than an SKB or equivalent case. The last couple of hunts I’ve flown to I’ve left the animal with a local taxidermist to salt and dry hide and prepare skull and have it shipped back later . After almost losing a grizzly hide because it didn’t make it back with me I just don’t trust airlines with a trophy.
Again , depending on what you are hunting if you want a skull mount you almost have to leave it with a local taxidermist because it’s illegal to bring any brain or spinal column material across borders into WV if it’s a cervid.
