For the people who are having their redemptions rejected and credited back:

Are these from accounts that previously had redemptions for the same award (2500, 1000, 500 or 100 miles)? This would indicate that they are only referencing by account, not by FF#, street address or whatever.

Has anyone ever had a rejection from a fresh new account that has only had one of each award to a max of 4100 miles per LSC account?
