From DOS, the lesser of 25% or 3 slots/ month for every month in which US Airways is hiring have to be piedmont pilots. There are examples in the LOA. This letter is signed by US Airways group and is binding in a merger however the new American has an option of renegotiating it if they need to. I've been told this LOA is not something that can just be ignored or thrown out like the RJ agreement was since it was signed by US Airways. If AA no longer wants it they will have to negotiate with us to modify or delete it.
