Not a fan of fully enclosed F cabins, much prefer the current one giving both privacy and a feeling of space.
Middle seat concept is also pretty ridiculous but I guess they found demand somewhere…
Regarding 1 row, it would make sense if they allocated the A330 on low F demand routes, and had 2+ rows on the 777/350.
Most airlines would have chosen to ditch F totally for low demand routes but this strategy would enable keeping a large footprint for F class within the network.
