Now, the LP crediting remains the same as the fare booked, but at least the SDC options were available and do-able.
Edit: I just went on to read the fine prints on AA.com, and nowhere do they mention fare class restrictions and nothing restrictive for status holders.
Domestic Same Day Confirmed Flight Change / SDFC / SDC / CFC / "Standby"
The new changes suck. No SDC at airport, only online unless have status. Online frequently fails leaving no options for numerous.
Same fare class isn't required. However a seat being available (even in same fare class) isn't it either. Basically AA decides if they will allow SDC on a flight by flight basis. You could have a J fare but not be allowed to SDC to a flight with J. Routing changes have never been allowed.
