You can check here, among other threads, for discussion of this (added: I think it's about the same thing, although it's not a "double miles" thing, but a bonus miles thing):

Unfortunately for me, my business travel has me going to NRT. The plus side is that it's a non-stop from SJC, whereas I'd have to have a connection through ORD for NGO. Wouldn't be too bad for the double miles but, when it's the company's dime...you do it their way .

Cheers.
