Just because an agent made an exception for you last time doesn't mean it can/must happen again. Data points on FT may be from Diamonds where agents are willing to bend the rules for their loyalty.
Changing routing AND without original fare class available for SDC is waiving multiple policies. And many agents will simply not do that.
Wrong.
You can SDC a FC ticket directly into FC if FC seats are being sold on the new flight. There's no fare class availability restriction for FC tickets, which is what the OP has (class A). [The same is not true for coach tickets.]
Also, you can change the routing on a SDC (but not SDS) assuming that the new routing is legal for your fare and that you are not changing from a connection to a nonstop. If you have a broken fare, you must go through every airport where there is a fare break.
These are the published rules. DMs are allowed co-terminal changes.
