I have (free) Life Insurance that's provided by my employer, but it doesn't cover death/injuries resulting from flying in private aircraft. So, for awhile, I purchased a life insurance policy from AOPA that covers ONLY death/injuries related to GA flying. That way, I got all scenarios covered. Their premium rate is available on AOPA web site, and quite reasonable.
Now that my networth is enough that a life insurance policy isn't warranted, I no longer carry the AOPA policy.
You should compare and see if having two separate policies (a typical one, and a flight-related one) is cheaper than buying one that covers all causes.
