Thanks SQ325! It was not was I was hoping to hear but I guess it is what it is. One question though, what does "CI" stand for? I have been calling SEN Hotline about once a week for the last few months, but SQ booking system is not quite as open as that of other Star Alliance members and they can't waitlist me. They said, I have to keep in trying until seats open up - if they ever do.
@lokijuh: Yes, we have booked "B" class simply because of the reason to be upgradable. I thought it would definitely work with an early enough booking, but I guess I was wrong...
