Thanks in advance.
This is probably your best bet. https://www.flyertalk.com/forum/trav...sk-thread.html

When you say for intra-US flights.... are you looking to use a SWU/miles-copay? If so, yes, it is C for Y to J and A from J to F. About a year ago, AA standardized their fare buckets.. so while it is called FIRST domestically, and BUSINESS internationally (for 2 class flights), they both use J for full fare, C for upgrade and U for milesaver awards.
