Also seems that the FAMs are in F because they want to be there because they're bored and uncomfortable with their jobs and not necessarily because they can see the cockpits as some insist.

Additionally, if the airlines were getting paid for the F seats, they wouldn't be squawking about wanting the FAMs in other parts of the plane, like say Y, because they were getting paid for those seats. Wanting them out of F and into Y tells me that they're not getting paid like CO says they're not.
