(De-lurk.)

Smoke escape hoods:

I've flown with my EVAC+ hood several times, including one return trip to the US, with no problems. It says "no compressed gasses" and "safe for air transport" on the container.

In fact, other than a smile from a Portugese security guard, I've never even had a member of airport/airline staff acknowledge its existence. My theory is that they don't want to have a discussion about fires on aircraft in front of other passengers.

Flashlights:

I've flown with my Streamlight TL-3 and Pila G3 with no problems. A co-worker has told of being questioned about a larger Mag-lite, but was allowed through with it (it was still in the packaging.)

Cutting things:

Apparently we're now allowed round-tipped nail scissors (blade length no more than 3cm). Accordingly, I've bought a pair of Fiskars straight manicure scissors (#9806033). They go through paracord easily enough, and I'm guessing they'll work on clothing too. It's better than nothing!

I haven't flown with these yet. Any other suggestions for airline-friendly cutting tools?
