Thanks for the repost and making it more clear. As far as $100 per hour for the AA contracts that is just par for the course. Claiming overhead when they rent the facitlity for next to nothing and even have the City of Tulsa paying the electric bill for them. Crooks.
A lot of the overhead consists of management personnel and support staff - people who are necessarily employed because of overhaul but who don't personally touch the airplanes and whose time is not separately billed.
When I take my car to the local GM shop, I have to help pay a lot of people who don't touch my car and thus are not separately billed, like the service writer (who makes big bucks), the girl who takes my payment (underpaid), the lot jockeys and the shuttle driver.
