If you are concerned about being saddled with a big helicopter evacuation bill, and you enrolled in Life Flight for $75, you might want to pony up another $60 for Airlift NW. I have both of these through my employer since I work in some remote areas (and my family would like me home, alive, at some point after work, or at least I think so, not just because I'm some unprepared pansy), and the reason for having both is this--We looked into how this works, and if you call for help, your SOS goes to emergency dispatch/911. They will send whichever helicopter service is closest and available. They don't ask which one you have insurance for, and wait to make sure that that one is available and then send that one. They send whichever one is closer and going to be faster. The services do not share this factoid up front when you buy their insurance.
