Sorry about any personal sentiment that reflects on lawyers....
No offense taken.
The real point is that insurance is not a gimme--it's a contract between the insured and the company. If the policy says, in effect, "this incident is covered", then they pay. If not, then no coverage. The reason that there are cases involving insurance companies is not that they are necessarily trying to avoid paying when they should, but because the language of the policy is often nebulous enough that different people interpret it in different ways.
For instance, in this particular case, the family (or at least their attorneys) believed that since what the pilot charged didn't cover his expenses, it wasn't commercially reasonable, and therefore couldn't be a commercial operation. Avemco's position was that it was a commercial operation, because there was a charge, and the policy specifically allowed sharing of expenses by people with a common purpose (much like the FAA allows sharing of expenses), but paying a fixed fee to go for rides didn't qualify. The trial judge agreed with Avemco and granted summary judgment (so there wasn't a trial); the appellate court agreed with the trial judge, and provided a very good analysis of their reasoning. They analyzed the language of other cases, where the "shared expenses" language wasn't there but commercial operations were similarly prohibited. It's really a pretty well-written opinion.
The bottom line is make sure that your own policy covers what you plan to do. For instance, I do Angel Flights now and then. There is no compensation at all--no one pays for any of my operation of the aircraft. Clearly I'm covered, so long as I'm otherwise covered (like current BFR, current for the operations, adherence to regs, etc.). Others do Young Eagles, etc., for no charge. But as soon as the pilot accepts any compensation, at all, the specter of non-coverage pops up. So check it out--it doesn't take much effort, and obviously the benefits are great.
