Everything about this flight was smooth and uncomplicated.
We decided to pay for our seats, about 6 days prior, to ensure we were sitting together and had some level of comfort for our flight.
We watched movies for the entire journey as we wanted to adjust to the time charge. It worked - we both generally sleep on flights, so this was a bit of a variation from our norm. It worked well, so it is a suggestion to travellers on this flight to maximize your time zone adjustment. We did go to bed early on the arrival night, to also assist in the change.
One note - the WCs were not un littered in the later phase of the flight.
