i recommend searching for "upper deck" or "upstairs" in an advanced search, and force it to do titles only. FT search sucks but advance search will get you what you need. definitely will be a better help to you. this question is one of those ad nauseum discussed topics, and i suspect you'll garner only a few posts here because we've all typed our brains out in the past about it. those past posts have tons of info. hope this helps. 82A is in the very front and IMO is a good seat upstairs. the only ones i avoid upstairs are next to the toilet and galley.
