Typically my price point I achieve to Asia in J is a lot lower. So this was at the upper end. I will ask at check in, and the last time I did so, as you state, it was much higher than the minimum. I will report on empty seats, if indeed I get the opportunity to determine such. I will ask how many are available.
As I have an onward connection, J would be nice, but for £922 I would expect both sectors, and I know the onward part is full in J. The real issue, is a very short connection, and that will be a problem if i miss the firstof 2 flights of the day, as the second one is also full in Y & J.
