I bought an MSR Dragonfly to avoid this problem. Not as quick to light or convenient as gas but it will run on paraffin or diesel which you can get anywhere. It has an adjustable flame too so you can cook on it properly rather than just boil things. Makes it a bit more versatile. Weighs sod all.
It can run on petrol or naptha by changing the supplied jet - takes a few minutes.
You can get gas in KAF, can't remember which PX, and then when you board any stampede flight onwards the gas all gets collected and placed in a bag that the loady stowes somewhere. A tip is to permi pen your name on all the canisters otherwise anyone can claim its theirs.
Note that it will not be allowed on a helicopter out of KAF but will be out of BSN (God knows why?!?!)
hope this helps
No Duff and certainly no Wahrage, I had to in-inspect 200 odd Coleman stoves and God knows how many Jet Boils. There out there to be used - unless your QMs Dept are a bit pants and prefers to store stuff rather than issue it.
