Are there any programs where this doesn't work? That is, where you link an account but a transfer gets rejected?
And is there a list anywhere of which partners are 'live' with Amex (points transfer instantly) versus which ones still take a few days?
CO, DL and VS are immediate, even from another's MR account to my airline account. NH take about 2 days. These are my own experiences, that I have seen confirmed elsewhere.
