See previous comments. Didn’t take this flight because my other flight was so delayed. Ending up on two other flights as a result and was more than a day late.

See previous comments. Didn’t take this flight because my other flight was so delayed. Ending up on two other flights as a result and was more than a day late.

6 hour delay and they didnt try to make up any time during an over 10 hour flight

Very good; seat made ready for bed after meal, a plus since one airline covered the seat at the start.

Entertainment was not good. Seems like liquor should’ve been advertised only beer and wine was even though I saw others getting liquor didn’t realize I could. And the food to me could’ve been a little bit.

Food choices perhaps not the best. Only offered beer and wine, when it appeared other liquor was available. Entertainment wasn’t so good.

They charged me over a $1000 dollars to bring two surfboard bags as check baggage. Inappropriate and I would avoid flying sgain

The experience on Fiji Airways was absolutely amazing. Streamlined. All staff was amazing. Pleasant. Friendly. Extremely helpful.

Business class Seats on the A350 from Nan to YVR were wonderful. The flight crew was okay but could do with better training. Toilets were clean but ran out of paper towels towards the end of the flight. The food/menu and the wine offered really needs considerable improvement. Dinner options were either Bolani, a beef sandwich (even this could be made much better), or paneer butter masala. Unfortunately, if you are not a fan of Fijian food, there isn’t much choice. Dessert was either turmeric ice cream or fruits but unfortunately, they were out of fruit! So the only option was turmeric ice cream. I’m not certain how many passengers like turmeric but I am not one of them. They need to cater to a more diverse group of people. Perhaps they need a new chef? The movies& tv shows were mostly older so I didn’t find that interesting either. It was however, fun to view the plane’s exterior cameras as we take off and land. The best thing about this flight are the business class seats.

Comfortable as one can get in Economy, food was very good, staff were super friendly & efficient.

Really liked the plane and business class seat. Food was ok but could be better. Service was very good.

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

The issue was with getting our boarding pases. There were issues with our arrangements that were made through Kayak. I am sorry to say that we will not use you again because of this. The flight itself was good and the flight attendants excellent.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

USB charging ports did not work on any of Air New Zealand flights

Economy was much nicer on the Air New Zealand planes.

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

Flew premium economy, well worth the extra. Much better seat size & space. Meals & snacks were lovely. Crew really pleasant. Internet is not great, not really useful for anything. Couldn't even send messages.

Everything was fine. Wish the wifi was free and included in the ticket price.

The flight we had booked was cancelled due to bad weather conditions, but we were lucky to arrive at the airport quite early and got a seat on an earlier flight. The flight was mostly nice, but there were some hefty turbulences towards Queenstown. One of the passengers behaved hysterically. It would have been great if the crew had done something to calm her.

Sitting in an aisle seat equals getting hit by food cart and spilled on multiple times Food: gross and minimalistic Crew: frumpy and kurt Sound on multiple entertainment platforms poor Not an earplug problem, system soundboard poor
