Upgrade using VS miles, credit to DL? Possible?
Hi!
I'm looking to book, and then upgrade one leg of a Virgin Atlantic booking (VS code, metal, stock ticket) using VS miles (transferred from Amex). But I want to credit the flights (well, the underlying economy class ticket's miles) to my DL account. Is this doable? Is there a risk that the flights post with a redemption fare bucket, rather than the underlying economy fare? Or could the flights post to the wrong account?
Any insights appreciated! Thanks.
