The problem with "Airline" is it didn't show enough about airline operations. I don't really care about hearing about drunks being denied boarding. I want to know about ops - How the luggage is routed under an airport. How the IT systems work. How jets roll in and out of maintenance. How staffing works. Show me a 'day in the life' of a fin # - Where does the jet go in a 24 hour period? Show me scheduling.... Show me an engine being swapped out... And on and on.

*That's* what I care about and what I would watch.
