Well for all of you who were waiting with baited breath for my report, it now looks like my A321 tomorrow morning has magically had the extra 2 rows of seats removed and it's back to normal config. Rather pleasingly, this now means that I have appeared back in Row 9 with TS so far keeping the seat next to me blocked, which is a result all round. However it means that I can't report back on how the densified A321 works in practice. Maybe another FT-er will get there first
