Roomy seats and crew is pleasant. Vegi food can be a lot better in terms choices. Inflight entertainment needs to have more options especially for 13+ hour flight. Very nice and warm blankets and seats are roomy than other A350 aircraft’s. Swift boarding and crew is pleasant to deal with.

Roomy seats and crew is pleasant. Vegi food can be a lot better in terms choices. Inflight entertainment needs to have more options especially for 13+ hour flight. Very nice and warm blankets and seats are roomy than other A350 aircraft’s. Swift boarding and crew is pleasant to deal with.

Boarding had poor communication. Passengers didn't get clear directions to prepare for Boarding. The plane was an older model which had some issues with operating the seats (the staff was great). Due to age the seat cushions were compressed and less comfortable than expected.

Fiji Airways always goes above and beyond. If anything I'd say the food was less enjoyable than in the past. But that in no way lessened the experience with the cabin crew or the excellent attentiveness and service they provided throughout the entire trip!

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.

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.

They will look to squeeze every penny they can out of you!! Pick your seat$$...bring luggage$$$$... if they could charge you for the air on the plane they would!!

The part that really made for a poor trip was that we checked luggage, and it took 1.5 hrs. to get our luggage. This made it so we barely got to our next flight. We were the last ones on board.

Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

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.

Aircon set too high so VERY warm and VERY uncomfortable.

Great! Flight was delayed by 30 mins but all was great. Thanks.

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.

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.

Overall, a great experience from food and crew. The only setback was that this was the Second flight from Air New Zealand within a week that was an hour late for boarding.

The air New Zealand employees who assisted us with wheelchair aid on Auckland made our transfer from flight to the next seamless. Also were amazing in helping with our luggage and customs in Brisbane.

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

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.
