Of a commercial airline flight. Is it just out of the question?

What you are trying to do is possible if you know a pilot and he/she has an
empty maintenance ferry flight.

I had the great fortune to ride on such a flight in a B-737 a couple of
years ago.

With no passengers the flight operates under Part 91 flight rules.

With passengers you are out of luck:
