Really depends on the outfitter and type of hunting. Hunted Alaska for moose and sheep. Outfitter had no game sacks or cooler - meat hung old style from meat pole outside and chunks cut off for camp meat. Tenderloin and loins eaten within 2 days at camp.
Moose are huge and logistics of shipping to lower 48 are expensive. Airlines allow up to 2 bags which mean if you check coolers, you have to ship gear home via UPS or bite off on excess baggage and overweight fees. Outfitter said most hunters only take cape and horns, leaving meat for outfitter, community and friends. Meat is not wasted but spread around the community, used in camp and feeds guides and wrangler's families.
I hunt to feed my family in addition to recreation, so I brought 2 coolers of frozen meat at 70 lbs each plus one duffle bag and gun case on airlines home - incurred $300 additional weigh and baggage fee. My friend took 2 coolers and shipped gear UPS home. We left 3 coolers of meat for guide, outfitter, pilot, Wrangler and community. Half the sheep was eaten at camp.
