Hi everyone - I've read through this thread, and appreciate everyone's great info & feedback. I am on DFW-HKG in a few days, and have the choice of 16D vs. 17C (with 17B currently empty). Row 19 is booked.

Solo traveler, OWE, prefer to sleep majority of flight, would be nice to have aisle access for occasional bathroom break. I am guessing based on people's feedback about the middle part of Row 16 sometimes getting a lot of pax foot traffic crossing aisles, waiting for lav, etc., that 17C would be slightly preferable - slightly wider seat, moveable armrest, "better" tray table - even though I might have to get up for 17A during flight? Anything else I am not considering?
