I am looking forward to trying out Swiss – but only when I know that there will be a good chance of the new C seat.
From my perspective, being 5’7” and 73kg, my preference is for the flat seat not angled. The current seat size is not an issue,
I also find it somewhat amazing that a frequent passenger survey survey has persuaded Swiss not to update their F product. Perhaps the survey was among their frequesnt travelling internal audtitors!!
