1 hour minimum is perfectly reasonable. I wasn't aware of that. Happy to chat more, just new to the forum so don't know how to navigate it fully. Message me if you'd like.
Agreed on the King Air.. there are several different versions out there and some are much nicer than others.. depends on the owner upkeep. The wheels up planes are new so i'm sure they're as close to 10/10 as a King Air can be. You're paying for that though.
With regards to the King Air vs. Jet argument.. I have no issue, but have many people who I fly with (including family members) who won't fly in ANY prop. Unsubstantiated fear, but a fear none the less.
