Here are the things that TSA might give you trouble over

*1L platypus (must be empty at the checkpoint)

- I can carry-on 100 mL, which is probably what I'll do, in my KK. The platypus stay folding up empty in my purse for emergency use with microPUR tabs.

*Ferro rod - Scraper may be confiscated as knife, and ferro rod may/may not make it through as it's a potential fire hazard. One conventional lighter (non-torch) or one book of safety matches is OK. You could probably get waterproof matches through, but the big lifeboat are probably prohibited.

-You're right on both. I can carry a non-refillable disposable lighter and one book of safety matches, for personal use. I read it as a regular book of matches, so ditched my storm-proof matches and Ronson jet lighter and added a regular book of matches.

*Chemical body/hand warmers - May be confiscated as potential fire hazard. Probably viewed in same light as sterno cans.

-I hadn't considered this, and you are right. Thanks!

*Hard case with prescription glasses, clip-on sunglasses and mini screwdriver - screwdriver = pointy object. Just because it's allowed in the rules, doesn't mean it'll make it past the checkpoint. The smurfs confiscated my Wife's embroidery scissors (3" overall all length) because they had a point, but let nearly foot long knitting needles through.

-Doh! Better safe than sorry, so I took out the screwdriver.

*Esbit stove and fuel tabs (Not sure if Esbit tabs are TSA approved) - Tabs are potential fire hazard. Definite no go. Stove, if used, may be prohibited because of fear of tab residue

-Agreed. I ditched it all. I can make an alcohol stove when I'm there if I think I need one.

*SOL mini fishing kit + safety pins - Fishing hooks = potential weapon depending on size.

-I think I'm ok, but ditched it anyway, just to be sure.

*Bug spray, sunscreen - Subject to TSA 3-1-1 liquids policy

-Right again. Small containers are allowed, so have been added.
