Must try that out.
I must say this worries me a bit. If both an award and an upgrade are I fares, how will 'the system' know that I had an upgrade and debit me the miles I should get for buying an economy (S in my case) ticket

. Especially important as I should get double miles as per the promotion. I guess I will find out soon, my trip is next week.
