I did an Etihad Airlines Transfer on October 12 and still have not received the miles.
I did a United Airlines Transfer on October 25 and have not received the miles.

I wrote to Marriott and called. They told me that the airlines have received the miles in the form of a voucher in which they gave me the numbers. They also told me to call the airlines to ask why they haven't posted-pretty funny. They also told me to wait 6 weeks and to get back to them if the miles don't post by then. This transfer process is a complete joke and has really made me turn sour on point transfers to airlines.
