I hunted Molokai for axis. Right next door.

I didn’t bring the meat home though plenty of folks have. Hawaii is a big fisherman destination and lots of folks bring their fish back to CONUS. I couldn’t imagine the outfitter and/or airport don’t have a system for keeping meat coolers or wax boxes frozen until ready to be loaded into the cargo hold. Have you asked your outfitter, assuming you’re using one?
