Not sure about that - I have had an op-up confirmed the day before when I did an online check-in (this was Y-J on HKG-BKK).</font>
I guess your flight was terribly overbooked in Y and empty in J. So what, when you online checked in, your reservation was shown as J? Or did they say "You've been upgraded!!" or some sort of a message?
