We donated most of our meat. One guy in our group had a friend who works at the nursing home in Kotzebue, we donated the meat to the elders there through her. We brought home a total of about 95 pounds of meat.
Each caribou we shot would yield about the same amount of meat as a really big bodied muley buck. They look much bigger bodied, but so much of their mass is lungs and guts, the meat is not that much.
Bone in regulation to my understanding means all the quarters and the ribs come out on the bone. That's what we did.
We had a lot of luggage, and paid extra for it. We each had a Kuiu 9000 taku bag plus two other pieces, either gun cases or totes. The Kuiu bags are oversize but held our packs, boots, and other bulky gear. We had our optics in our carry-on bags. Coming home we had an additional antler box and a fish box with almost 100lbs of meat.
Going again, even though our Exo or Seek packs are technically oversize for carry on bags, we saw lots of other people use them without issue. We could have saved some baggage by using them that way. We took all our own gear and food from home and had a fairly comfortable drop camp. Not over our weight limit GE and us agreed on, but bulky. There are ways to reduce bulk by either renting camp in Kotz or taking more of a backpacking camp. To us the additional hassle was worth it to have our camp kitchen and area outside of the tent to hang out in bad weather. We had camptime Roll A Chairs, a 10x10 Seek tarp, and a plastic tote for a table. When it was socked in and raining and we couldn't glass we spent a fair amount of time out there. We also had a 28lb Cabelas Alaskan Guide Instinct 6 man tent that took up most of a tote. Flying into the field we moved a lot of items from the totes into our packs or Taku bags and took only one tote.
For fees I'd just check Alaska air. I don't remember for sure and they may have changed. Covid was changing things so regularly before our hunt I'd hate to give outdated information.
