It's a long haul. The bulkhead seats on the way out were good. TV monitor was on the bulkhead, which meant no need to move the TV panel from beside the seat. Headsets were noise-cancelling most of the way. Here is the weird part--on the NRT-SIN leg, they were not. And I had packed mine away in check-in. The stewardess appeared puzzled that noise-cancelling headsets were available for premium economy.
There is a legrest that is best described as a calfrest and individual swan-neck lamps for reading. There was wifi on the outbound. Oddly enough, the plane had no wifi on the inbound and I had some work I would have paid for.
Service was friendly. Stewardesses never ever forgot what they promised.
Transfer gates and lounge are close to each other. Although I should add that the lounge was almost completely packed inbound.
Improvement? Well, on the SIN-NRT flight, the stewardesses greeted us at the plane and that was it. All other airlines would direct passengers to the correct aisle. These folks did not. It led to confusion and as I was at the bulkhead, people crossing over. A little annoying having to be main street.
