Here is a Citi TYP transfer data point. I just transferred 100k TYPs from my premier card to Asia Miles. The transfer took 1 business day (I also transferred 60k MRs which took 2 business days).
I was able to redeem the 160k asia miles for 2 rt business class tickets from jfk to madrid on iberia valued at $3800 each. The taxes came to $60 per ticket.
