I am sceptical about the A380 going to KIX. I recall a couple of years back when they announced KIX would get F with the 747 and I had a trip booked only to get TG'd a couple of weeks before travel when they decided that KIX would not get F after all.
KIX was also the planned technical stop for the BKK-LAX run on the first go-round of TG's desire to pull the A345.
I was booked in Y+ and bumped to C when they switched. Of course the switch didn't hold and was kept in C when everyone was ported back to the A345.
