Great report

I agree - I've only flown LH J, which I've always found to be a let down, with similar privacy issues. While privacy issues might be acceptable for J, it's certainly not for F.
2+2 upper deck seating is what most airlines have in J, isn't it? Eg.
this really old OZ J cabin on a 747 which I've been on a couple of times.
