Interesting, I did about 6 flights in LH F and LX F in late 2011 (mostly LH), and LH served the L-P Millesime (2000 vintage) while LX served the Grand Siecle (unsure of vintage). I enjoyed the Grand Siecle considerably more than the Millesime. It was one of the few things I enjoyed more about LX F vs. LH F (except of course the old LH F seats which I had on a couple of flights then).
