These figures are incredibly hard to make sense of, thus a rather lage caveat has to apply to my comments.

The first flight looks generally open, F will probably be the fullest of the cabins. Prob no op-ups to be had.

The second flight looks pretty open - except in J. Prob op-ups from J-F to be had.

The figures are hardest to make sense of in respect of Y. The numbers only ever go up to 9 - which with 300 or so seats is difficult to make sense of. Book a seat in the centre block and you may well find you've got the row to yourself. But there's really no guarantees. Best option is to ask at check-in what the load is and work from there.
