AA FLIGHT OPS
I worked with AA Flight Ops for about four years in the main operation, that was about 9 years ago. In addition to doing the usual crew briefing function, and met briefing, we also used to liaise with CFMU, (SO read up on Slot Message formats i.e, SIPs, etc) and we also used to do the weight and balance for third party airlines. At the time we also handled some Eastern European Airlines, so we were also doing manual ICAO despatch.
A good Company, but Flight Ops is considered a "Plum" job at AA, and competiton may be intense.
PM me if you need further info, as I am still in contact with some/most of the guys there.
Cheers
