I think 81A is the best seat on the upper deck. You really have to strain to look out a window, but that's the case with all the seats. There is a little area in front of the seat where you can toss magazines, newspapers or what not, helping to reduce clutter in your own space. And the best thing is that you are served first, which is very nice since service can be slow if the cabin is full due to CX's previous reduction of one FA.

I don't find the FAs walking past to provide service to those in the flight deck bothersome in the least. I'm guessing that people sitting further back in the cabin may get their foot bumped somewhat frequently when people head to the lavs.
