A little while back it came to everyone's attention that many air charters will not let you carry the jetboil fuel canisters on their flights due to it being classified as hazmat. i guess the rule was on the books for a while but not enforced.
I was going over my gear list for my september drop off moose hunt and on the list I had my Thermocell bug deterrent and spare butane canisters for it. Does anyone know if these are allowed? I dont think they are any different than a cigarrete lighter but I believe they are pressurized. I dont want to call and ask 40 mile air yet in fear that they might start asking the TSA and get them banned also.
