So, yeah, TSA needs to be remembered.
I figure I'll be in town mostly, with a few flights. Since I'm not the pilot, I figure having survival stuff for myself, figuring that he'll have his own gear. A PLB is a good idea - I wonder if the bush planes/medivacs will have a locator beacon? I'll look into a sat phone too.
Do you really want to rely on someone else for your safety?
You can send firearms as checked luggage, but there are requirements.
I really am staying away from obvious, because that can become specific to each area of AK and relies on area experience.
Second time thru for my suggestions: GPS, PLB, SAT PHONE, (last two can be rented I think).
CAMERA!!! nothing to do with survival, but you want to remember this chance of a lifetime right?
