Coming back from Europe? Want to share the costs with someone you don't know?
Hmmmm, going to search his luggage? Just taking him one way? From Holland by any chance?
Any private pilot in his right mind should have nothing to do with flying passengers they have never met before.
The same should apply to any passenger wanting a jolly with someone they don't know, regardless of their "claimed experience".
I would give it a wide berth....regardless of what the "law" says.
