Was very impressed with Air New Zealand when I flew their AKL
B767 service late last year, as well as the B747-400 service on from LAX
. Very attentive and friendly cabin crew in economy, meals were fine and the cabin crew working our part of the ecomony cabin even remembered my other half was drinking the Merlot wine rather than the Cabernet Sauvignon !!
Other airline economy class service I have been impressed with are Emirates, Cathay, Singapore and Malaysian. Virgin Atlantic was fine as were some of the North American carriers. I know others will beg to differ, but I haven't had a major problem with the economy service across the Atlantic on either Air Canada, Northwest, United, US Airways or American.
Although, as a personal observation, I have found the economy service of the 'Asian' carriers I have flown with to be somewhat superior to most of the others.
