Did the same hunt as you last year,muzzelloader elk in Co. Flew from Rochester NY to Denver.Ended up shipping my hunting gear(everything but firearms)back UPS in a large plastic tote.Had an insullated carry on freezer bag I purchased at Sam's Club which I fit about 50 lbs. of meat in,and then bought a cooler and packed it with meat,about 70lbs.Check with your airline as to weight restrictions.I paid an extra $25 charge for being over the weight limit but it was worth the extra charge to bring back more meat.I was able to get over 120 lbs. of prime cuts home for the cost of shipping my gear about $60 and the $25 dollar airline charge.I donated the remaining meat mostly burger to the needy.Good luck and have a safe,fun hunt!
