I recently flew Air New Zealand for the first time in decades from Perth to Queenstown return via Auckland, and was extremely impressed. The cabin fitout was very sleek and smart on both the 777 and A320, and I was blown away by how comfortable and roomy the economy seats were. So much leg space in front, and such wide seats, so lots of space either side too - and this was both on the double-aisle and single-aisle flights.
Cabin crew were all professional and friendly, without being over the top. Didn't bustle around unnecessarily, but at the same time were there when you needed them, and came down the aisles several times serving water and refreshments (even for those of us who had not paid for a meal). I also loved the little lollies they gave out at the end of each flight - a nice touch and very yummy! Announcements were always clear and concise. IFE was excellent - a good variety of programmes and music.
If you are arriving into Auckland on an international flight and then transferring to a domestic flight within NZ, Auckland airport can be a little bit of a shambles, especially if you are doing it for the first time, as I was. Basically you have to clear immigration, collect your bags and then figure out where to go, as signposting is not very clear at all. If you have enough time, you can drop your bags off in Zone B at the international terminal where you arrive, or if not, head straight to the domestic terminal (there is a shuttle bus every 15 min or otherwise it's about a 5-7-minute walk following a green line to the domestic terminal) and drop your bags off there. I did my bag drop in Zone B at the international terminal but I had to ask a staff member as it was very confusing, and I had quite a tight connection so it was a bit stressful.
Apart from that though, the airline itself and my experience as a passenger onboard was outstanding - it well exceeded my expectations. Their online mobile check-in worked perfectly, and I also used their 24/7 chat on Twitter and received prompt help with my pre-flight query. Very pleased all round, and would certainly never hesitate to use Air NZ again. Thank you!
