The Swiss seat plans now show 15 rows of 2+3 seating on 319 and 320's, but curiously not 321's.
I am positive my 320 flight yesterday featured these, but don't remember seeing them on another such flight ten days ago.
Is this a new feature? I am quite sure Swissair C did not sport convertible seats on A32x.
Also, has any other non-elite passenger experienced being systematically seated at the rear of the plane when travelling in coach, on a feeder flight to another airline's long-haul?
I experimented with this by checking in way early (among the first 10 for 2 flights), and still ended up in row 2x (at least in a window or aisle).
My unusually high ratio of free to paying LX flights may have earned me a black mark in LX' computers, but this certainly does not tempt me to fly longhaul Y to one of LX's few remaining US or Asian destinations.
