I don't like flying either. Mostly, though, it's clothing and footwear that will get you off the plane in one piece.

Provided you stay below the maximum length (described on the site), you are allowed to bring paramedic shears and small needle-nose pliers in your carry-on. I have also carried a braided wire saw, though not recently. One Bic lighter is permitted.

Ferro rods are sometimes confiscated (some screeners are unclear on the rules, probably because some ferro's have a sharp metal striker).

Ditch the esbit stove and fuel tabs.

Bug juice will be part of your maximum liquids allowed.

I strongly suggest putting any "items of interest" in a ziploc bag and placing it separately in the tray. This speeds up screening immensely. Otherwise they have to dig through your entire bag.

P.S., Sorry for your loss.
