I just called citi and confirmed that if your Custom Cash points are merged into your Premier Thank You points, these Custom Cash points are stilled flagged as 'Custom Cash' points and can not be used as points transferred to Airlines. This makes Citi not as competitive with Chase where your Freedom points can be merged and used as Sapphire ultimate rewards points with no restrictions. This is contrary to what I have read as the advice here and elsewhere. Could it be people just think these Custom Cash points are not tracked differently by Citi? Or does this Citi manager have it wrong?
