Also for what its worth. I take may bows and arrows along as checked luggage. I use a small plastic container to stuff the arrows and a wool (asbell) takedown case. Last fall I was able to fit in a riser and two sets of limbs , plus stringer,strings,ect. So I fly with what I need to hunt, apparel wise. This bag will be where you will want to stole away the bear pistol. Amazingly easy to fly with. Unloaded and locked with ammo in the original box. You can read that on all the airline websites. You can't fly with bear spray in any manner but you can get it up there. I am a pistol guy.Kevin has great experience and suggestions on bear protection. I keep my binos and camera with me in the carry on bag so I don't have to worry about thrown bags. There will be many details but that's most of the fun.
