I am flying R/T SJC - NRT. I have coach tickets, but I may upgrade to biz. I did a search as to what were the best seats, but most of the posts on this subject were from quite awhile ago and with the MRTC and MRTB programs, the posts may be outdated. Could anyone who has flown this route recently make their recommendations as to the best seat to have in coach and/or in business class. Thank you very much in advance.
