Flew premium economy on a new 787 from Perth to Auckland. Premium economy was very comfortable and better than we expected. Entertainment was good and service was excellent, the staff were very nice and professional! There was only one negative aspect, the pillows were too big, which made them uncomfortable! The only problem was our original flight was cancelled due to maintenance problems of the 787 fleet and there was some difficulty getting rebooked for the next day flight. After much difficulty with emails, we finally managed to get service from the facebook messenger account at the second try.
