Do you know if they actually close the curtains separating the two C cabins inflight, where the mid galley is ? (long haul, NA -> TPE if that matters)
I wanted to choose a sear in the rear C cabin as it seems will be smaller and does feel more private. The only thing that may be of bother would be the lav, but if the curtain is not closed then it probably doesn't have too much of an effect.
