I just turned down a very similar situation.
A pilot friend owns a Mooney, and doesn't have his instrument rating. He asked a flight instructor to fly with him 900 miles to the south to pick up a puppy, wanting the security of another pilot with an IR. The CFI wanted to charge him $300 per day x 2 days to do so. I 'm figuring the CFI was going to claim flight instruction for the flight. So this pilot asked me instead, offering room and board, all expenses paid, but not wanting to rack up such expense ($600) just to take along an IR pilot. I didn't go, but I still wonder if that flight would have been Part 91 or Part 135?
