I travel about 2,700 miles back home each year to go hunting. 1 connection and total trip time usually about 12 hours. I am lucky in that we have access to a freezer. We debone, vacuum seal and freeze. I pack in rough totes to a total weight of 50lbs and zip tie shut- if there is a little space, stuff full of balled up newsprint. The rough tote weighs much less than a cooler, so you can transport more meat. Always has made the trip still frozen solid by the time i get home. I thaw and do the finer cutting at home then refreeze. never had any issues with quality/texture of the meat. If you have access to a freezer you may want to give it a try. Just be sure to be aware of how much time you have in your trip, it can take a day or two for the meat to freeze solid- faster if it's cold outside and your can spread the meat out in a garage or other covered unheated place.
Dave,I bring my moose meat back from Alaska, all of it. It some of the best meat there is. Freeze your meat, throw it into a good cooler/s and check it in as baggage. It will be fine.Terry, 540+ pounds of moose meat lasts me about two years. This is about 480#, the other 60#’s went into the other freezer. If hunting with a partner who did not get a moose and is willing to check in half your meat, you can almost fit one full moose as extra baggage before you run out of the allotted number of boxes. You do need to ship most of you gear home. Biggest drawback with checking meat in as luggage is getting the meat fully frozen before your flight home. Often your travel time with layovers and delays can exceed 12 hours. When hunting solo, you cannot check all the moose meat, best option for me is flying the meat home vis Alaska Air Cargo. I have my meat processed, boxed, frozen, and shipped by AAC by my meat processor. It is a lot less hassle and headache. To be fully honest, after field dressing all the moose meat and packing it to the air strip, I am too exhausted, both mentally and physically, to want to deal with any more logistics the absolutely necessary to get my meat home.
