Unfortunately, that's very typical. Many policies I sold wouldn't even cover someone flying a chartered (135) or corporate (91/91k) aircraft in even the largest of stuff (Geeeeeeeeeee). Normally you can get a rider for 121 if you're a pilot, if you're not normally the policy will cover you flying on a 121 air carrier plane.Also check on your life insurance policy. I am 5000+ hour ATP and my life insurance will not pay out if I fly a GA aircraft. If I am flying a company aircraft under 121 then it isn't a problem. State Farm's view GA flying is that it is very hazardous to one's health. I even had to get a rider just to cover my 121 flying.
It can be very expensive....very expensive.
