I've been a smoker for way too many years now (please, no comments I already get enough from my daughters) and over the years I've bought or been given lots of different kinds of lighters.
I carry a Zippo every day. In my packpack, BOB and campkitchen bag I carry spare "Bic" type lighters and waterproof matches. If I could find some I'd also have the old fashioned strike anywhere matches.
As for re-fillable butane lighters I've been given a couple of really good ones and for some reason I've never had any luck with them. Seems like they always wind up leaking and I am constantly re-filling them.
For someone that isn't a smoker and wants to just have a lighter in their pocket for emergencies I'd go with the Bic types. Cheap, lighweight and unless they are completely soaked thy work. Downside is that in high wind they are difficult to keep lit.

To a point. I took my Zippo on a flight during Columbus Day weekend (filled it up before leaving) and then took it out for the flight during Thanksgiving. Before filling it up it did light, but I filled it up just to be safe. During the time between, is was in my closet in the Otter box as I EDC a Brunton Helios.

That may be, but only the Zippo Otterbox is mentioned in the TSA rule exemption I listed above. It applies only to Zippo lighters. The way I read it, butane's are still banned. The Colibri box may be DOT approved, but there is not a specific TSA exemption, so I would not risk it. Especially with an expensive Colibri.

At some point, the other lighter companies will wise up on Zippo's special treatment and probably obtain their own exemption. But I really think the issue at this point is liquid fuel vs. butane.

That's been my only criticism with my Zippos. I can't seem to get more than a week out of a fluid fill up here in Florida - and that's with no or very light usage. Its obvously evaporating. Has anyone had better luck?

That is why I EDC a Brunton Helios. I only carry my Zippo after I fly some where.
