Air NZ
Recently got back from LAX with wife and two kids, found cheaper tickets with Air New Zealand, Premium Economy direct LHR-LAX. The flights (there and back) where one of the best we have flown. It was a 747, we where seated upstairs. The inflight entertainment was great, individual and full of choice both for the kids and the grownups. Food, believe it or not, was one of the best I have had on an aircraft, New Zealand Beef filet. Quick check in at Term 3 as well. It was truly a pleasure and almost £600 cheaper for a family of four compared to VS Premium.
