I do not like the 3-3-3 configuration of CO 777, but if the flight is not too full (which has been the case on my trips to NRT) it is best to try and get a row to yourself. Due to bathroom configuration row 32 is horrible. Always people standing around waiting for the bathroom plus the constant suck-whoosh noise of the toilet flushing. Also, the aisle jogs around the bathroom so 32C is a real horror story. The WORST seat is the last row in the middle, in front of the toilets (if the numbering flowed it would be 31 DEF, but I think there is a break in the numbers at the toilets). People stand behind you, yack, and bump into your seat. The worst!
