Cabin Class?

If you can stand up, it is cabin class. Club seating does
not make "cabin class."

I never heard that stand-up headroom was a requirment to be termed cabin
class. I've flown several airplanes over the years, such as 400 series
Cessnas and some small-med turboprops, configured for both airline and
charter/corporate use, all of which were termed cabin class by ops, mx, and
the Fed, but none of which offered stand-up headroom. There are numerous
exec jets that don't offer stand-up headroom. I don't pretend to know the
exact specs, if any exist, but I don't think stand up is one of them.
