About 1 hr before flight, noticed the Y seat (KL doesn't have Prem Eco on this flight). Tried to get resolved at help-desk, but they said "only one seat available for upgrade; and no aisle seats in Eco Comfort". We ended up with window/aisle on the 330 in Y (had I noticed earlier in the lounge stay probably could have done something to be rebooked...alas...). We did get home early and were able to stand by for a better flight home, so there's that...

Where do I go for the refund of the paid upgrade ($450x2) and the downgrade from the baseline ticket(Premium Eco to Eco)? The upgrade acknowledgement does have a refund tab, but does that hinder the case for my downgrade?
