I'm not a big "let's push an upsell all the time" kind of guy. But there's a point where I think we should evaluate the adequacy of what what's commonly presented to experienced pilots.
The "baseline" coverage when it comes to personal aircraft insurance is $1,000,000 Combined Single Limit for Bodily Injury and Property Damage limited to $100,000 each passenger bodily injury. Yes, coverage is available lower at lower levels. And coverage at higher levels is usually available. But the measuring stick really begins at $1MM/$100K.
I want to make you all aware that increasing that passenger bodily injury sublimit to $200K is often available for Mooney owners and the cost to do so is normally between around $70-$200 annual additional premium for experienced Mooney pilots. Not expensive at all.
One thing to remember is that the definition of "passenger" in most aircraft policies will include third party crewmembers. So the CFI providing your flight review or other training will also be subject to this sublimit.
Getting $1MM for Bodily Injury and Property Damage Including Passengers, without a passenger sublimit (often referred to as "Smooth") coverage may have to be looked at differently as more companies evaluate the age of aircraft in whether or not they'll offer this coverage. But it's still available for most Mooneys from several companies. The insurers with high quality policies typically have this coverage level available to owner pilots that have logged 300-1000 hours total time.
If you'd like to evaluate a higher coverage level, keep in mind that you don't have to wait for renewal. Insurance companies offering higher limits can endorse this coverage change onto an existing policy on a prorated basis.
