I was originally booked in F on CX885, until CX removed the F cabin and bumped me to J. So now this issue brings double suspicion. If CX cancels this flight, I would try to use this to get back my F seat on another flight........ or else I'd surely be happy to (hopefully) have the entire J cabin. :P
