Premium Economy for a.long-haul flight was worth it for the extra room. It is a 2-5-2 layout, so unless you have a family, get a seat in the 2-seat section. Nice slippers and goody bag. Food was tasty, although it seemed a bit repetitive (i.e., each meal used the same ingredients slightly re-configured). Staff were excellent.
