Going back to 2010 I flew an open jaw return CDG/SIN (AF) then MNL/AMS (KL), my first times on B777's, AF was a -300 night flight with 10 across seating, perhaps the most uncomfortable flight I have ever had to endure, the return with KL was a -200 with 9 across seating ... ahhh, luxury ... Thereafter I believe KL went to 10 across seating also.
I swore then that in the future I shall NEVER fly in a 10 across B777 again, I shall check aircraft types and seat plans before booking, and it wasn't about fare, booking AF/KL (from/to CWL) I paid quite a significant fare and I'd have expected better.
