It's good to plan ahead. I can't answer the question about flying, since last time I went for elk in Colorado, we (5 of us) went by pickup truck with a camper body and figured if we got one or two elk we could get it froze, packed and lash it to the roof of the camper. Poor planning, we each got our elk, two bull and three cows. We ended up driving to Golden CO where we rented a uhaul trailer and got a bunch of dry ice, drove back to the base camp area, filled the trailer with the 5 quartered elk packed surrounded by dry ice and headed home to NY. Came thru fine, no meat damage. Nothing long range about the hunt. All taken at 300 yards or less, with one 5 point that taken at about 50 yards, less than 150 yards from our camp.
