Using DL Skymiles as the ST flights account. I did notice that some great redemptions are availbale on the FB platform, including TATL for 15k and under. As I have read on some threads in various forms that AF/KL redemption tickets could be voided after transferring points from say, AMEX, would anyone know whether this practice is still very common? Would I have to keep account open for a while before making such transfer? Was thinking to open a FB account and transfer points from AMEX for such redemptions.
