OK. Then it's different from what I experienced at check-in the other day. I was on an aircraft with old business class. And they told me they wanted to upgrade me to first class because it was not with NBC. Since space was not available in F then, they then said we telexed HKG to upgrade you on your next flight (or to issue an upgrade voucher for your next flight -- I forgot exact wording). I was upgraded to business on my next flight. I was using an award Y ticket issued by a CX partner.
