That is why the ones I carry are flint fired. Plus even without gas you have the flint sparks available. The reason they are not allowed on planes is that planes are one pressurized to between 5 and 10 thousand feet. Most lighters are set to operate at 1000 or lower. Even if it is adjustable that is where most people set them. At the lower pressure they put out an almost blowtorch flame. Very disconcerting. Now with the overblown security they figured any butane source could be used to inflate a container to make a bomb. The explosion from one is not that impressive but several combined could be significant.

But even the the venerable Zippo will cause prioblems if it is overheated. Throw any lighter in a fire is not a wise thing to do. And most problems you here about is some ding dong playing with it in his pocket. If a tight weave the gas can build up and can cause a respectable fire ball in a very disconcerting location.

On most disposables the biggest hit most people clam is they leak and are dead after long storage. Usually this is because of the way such as packing in a small kit they are stored. What ends up happening is the fuel release level is slightlty depressed. Being aware of this and taking the precaution solves this. I found a lighter in a jacket that I haven't used in about 5 years. It still works fine.
