Since the Kenya Airways switch to Asante, I'm not able to add my number in a DL booking. Did anyone find a way to do it? DL chat even told me that they are not partners, so I'm not seeing that as a reliable source of information.

Perhaps we have to wait for the DL IT to catch up (still says Flying Blue and complains about an invalid number), but I'd like to be able to use this sooner rather than later
