I enjoyed the first season, but as a "plane geek" the kinds of things that would have interested me just didn't make for good television, and were never shown.
I wanted to learn about airline operations - Routes, staff scheduling, how you turn a 737 around. I wanted to learn what SW does when they strip down a plane for service and put it back together again etc.
I wanted to follow a piece of luggage - From when you give it to the agent and it disappears on a conveyor belt to when it (hopefully) pops out at the carousel.
I wanted them to follow a flight - From the craft arriving at the gate to its landing at another gate and push-back for a new flight. EVERYTHING that happens, from passenger loading to catering, to filing a flight plan to comms with traffic control etc. - Then what happens in the air with ATC routing etc.
They never showed much of any of that - Just drunks, white trash, and employee parties so I gave up on the show.
