Gents--the flying service Mike and John use prohibits the ISO cans because of their status with the FAA. Most of the smaller outfits in AK are not regulated like they are. It is not a blanket statement. Check with your flight service. I always pick up a couple cans for my Jetboil when I get to where I am going and leave the leftovers for them when I am done. My flight service last year had two Rubbermaid totes filled with them for me to choose from...
I love the JetBoil, I never cook in pots and pans, I just boil water for everything. Easy clean up, no scent to attract bears.
