I had to change my routings a bit after issuing the ticket as my plans have changed.
I initially had BKK-SYD route on BA, but now I have to do NRT-SYD.
I believe NRT-SYD is operated on A333 with QF and B744 with JL.
I just flew to DEL on JL 744 and the flight was very good. J was 50% full and F section was sold as J and allocated to elite members (when I asked the FA gladly showed me to an empty seat in F section and asked me to sit there... but since there was another person sitting in the window seat, I didn't want to disturb the guy... I will be sure to ask for row 1 on my return

).
So, anyways,
which will you choose? QF J or JL J? Both flights leave around same time so schedule is not an issue for consideration.
*Note that I have to waitlist for QF flight as it's full in D class.
*Note that I will fly QF to EZE from SYD few days after this flight.
*By the time I fly back to NRT, I would have been on three consecutive JL J flights in 777 and 744.
