All was good, the only thing was it didn't run on time.

All was good, the only thing was it didn't run on time.

Overall excellent but the Captain kept the seat belt sign on for far too long, especially at the beginning and end of the flight. It was 2 hours after take-off before the crew were able to start the service (on an 11 hour night flight, reducing our sleeping time) and the seat belt sign on went on during breakfast (90 mins before landing) and was not turned off again until we landed. This made for an uncomfortable journey of trying to limit fluid intake because it was unclear when the toilets would be available for use.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Carring crew, nice ambiance of the cabin, comfortable beds, good food well served. We liked everything.

The pilot tried to make up for lost time due to delays that were out of her control. She communicated the issues openly and clearly and made every effort to do what she could to alleviate issues.

2 of the 6 economy toilets were out of order. Drinks were not offered often enough - you have to order on-screen, which is often unavailable. Snacks and Milo ran out very early. Crew was fine but I think there was a sticking issue

So here's the rub - my flight was booked through Chatdeal even though I bought it under the Kayak umbrella. All the return flights were theoretically through Air New Zealand, however except for the initial leg from New Zealand, they were all partnered flights. So when I arrived at the airport in New Zealand they could only issue me my ticket to Fiji. Once in Fiji I had to do some serious leg work and finagling to get my ticket to Los Angeles through Fiji Air. This included a monitored covid RAT that I wasn't aware I needed to do. So I gave the score I did because of the complexity and annoyance created in the process of getting a boarding pass for my Nadi-LA flight.

The only thing that was less than excellent was the food server at dinner. (I had the chicken.) It wasn't that it was poorly heated or in difficult-to-open containers; it was just that it had a very peculiar taste. And I use that to describe not just the main course but the dessert as well. Very odd flavours for what seemed to be a mainstream item. I did like that the airline offered us a free glass of wine. The breakfast omelette wasn't bad, although it was quite bland.

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.

Better connections, much better cabin crew, much cleaner cabin that Qantas, American and probably other carriers.

Better connections, much better cabin crews, much cleaner aircraft than Qantas, American and probably others.

Fiji left without me because American Airlines was too stupid to get to LAX on time. Fiji should have offered a standby on another flight but they told me tough luck. I will never fly with this company again.

The A350 aircraft business class experience was very good. Comfortable and well appointed pod, and supplemental bed pad available for sleeping. Food was very good.

Business class seats and amenities were excellent, crew very attentive. Slept well. Food good, lounge experience nice. Would fly them again. A350 aircraft excellent, very quiet.

The flight attendants were extremely friendly and helpful. Everything ran on time. I highly recommend Fiji Airways.

The experience was lovely in every respect. The crews were delightful.
