Left on time , arrived on time. Staff was awesome!!!!! Great flight!!!!

Great food, wonderful staff made a long flight seem short

Everything was great . Arrived on time was smooth plane was clean. Crew/Staff was friendly and helpful.

Everything from the staff to the comfort of business class was excellent. This is one of my new favorite airlines.

Ticketing said dinner for the almost 14 hour flight and we were delayed an hour. However, onboard we were only served a sluce if pizza bread and a cookie. Not at all dinner and insufficient for a long international flight. Breakfast was good.

We have had an absolutely horrific experience so far getting home from Australia on a $18,000 + flight we booked with you. The flight did not deplane in Dallas because there was no available gate or staircase. We sat in the plane for 3 hours waiting to deplane. As a result we missed our connecting flight to New York. American Airlines put us up in a hotel several miles away. We waited 45 minutes for a shuttle and The shuttle driver was horribly rude and unhelpful. They offered us $70 vouchers for food but actually there was no food left when we arrived minus some chicken nuggets and corn dogs. It was awful. Horrible way to end a vacation. There has to be accountability here.

A bit cramped in economy and the people in front wouldn’t put their seats up during meal service, crew did not help with that and I felt they could have done more about it.

The airline is ok, but it needs to improve it schedules.

Again, Fijian hospitality was genuine, very comfortable, only improvement would be the entertainment. Why Do they only have 5 episodes of TV shows and from like season three...

Fiji Airways was amazing, will definately be lfying them again. The "Fijian hospitality" is not a catch phrase, it is genuine. the only things that could be improved is the entertainment. Not a great choice of movies, and the TV shows only have about 5 or so episodes, and often of a random season.

Both my wife and I thoroughly enjoyed our return home from Tokyo to Auckland and onwards to Palmerston North. We would recommend using the Premier Business class for long-haul travel, any day. Well worth the extra cost. Cabin staff were exceptional, Thank you

The Air New Zealand product is terrible, it's as expensive as a Jetstar ticket with add ons but with surely staff and old aircraft.

Great service. Food could be improved but overall a very good airline

Wonderful trip. Everyone from checking in to the gate to the flight itself was amazing - kind, helpful, and has a beautiful smile.

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

All good, except entertainment system could have been better. More choices.

Your entertainment could be better. I flew on Air New Zealand in January so was expecting a better choice in February...but no luck. Same choices and also could have a better selection. Otherwise, lovely service, the purser came to our seats to welcome us. Overall, very nice. Direct flight from Auckland to YVR was fantastic!

Air New Zealand over sold our flight and tried to bump us to yesterday. After several calls we got booked to United about 6 hrs before our original flight. No apologies!
