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.

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!!

.very good and as I needed wheelchair assistance all staff excellent.. only suggestion is get rid of those plastic chairs hard to ride in and staff have trouble compared to others. Everything else very good experience. Will use Fiji Air again.

In-flight entertainment options could use a refresh, Consider a tie-up with Spotify for more current music and with IMDB or other service for newer selections/movie ratings.

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.

The food was not as good as Air New Zealand. The veg pasta was pass-able but the veg cibotta sandwich was dry, hard and not up to par. The coach staff were attentive and accommodating.

Air conditioning was turned to the wrong setting. Way too hot. The entertainment system kept resetting and didn’t work half the flight. Said something to the crew. They didn’t do anything to help. Plane had a mechanical problem that resulted in 2.5 hour delay. Boarded the plane, had to disembark and get back on.

I was trying to get confirmation on if my luggage was going to be moved to the earlier flight (I requested standby to get home earlier) and was unable to get help from those working at the counter. The request to be moved to an earlier flight was handled smoothly through the app and appreciate the ease of the request.

Do the bumpy weather the whole trip they were very few times when the seatbelt sign wasn't on

Great except paying $240 usd for 2 pounds over on a checked luggage. Outrageous.

Like: Aircraft was better than others I've flown in. Crew was great, food was very good. Air New Zealand is now my favorite airline. On our long flight from AKL to YVR there was enough room for those of us in Economy to stretch a bit. My sister is disabled and they took very good care of her and me. Best entertainment offering of all the other airlines. Not so much; Flight from AKL to YRV was delayed BUT they recovered really well so no complaints here. Pretty petty point to complain about. Only negative I have. I will recommend to friends.

Nice friendly staff and crew. Love the 787 flight. Get meals and lots of drinks!

Great entertainment options on the screen. uSB A and C chargers. Free WiFi! Crew were excellent.

Service was excellent and they’re very helpful and nice

Check in crew member was very helpful, nice and excellent service👍

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

Not great. The inflight entertainment was all on an app, and I did not want to watch a film on my phone. Also, the range of options of films was limited.

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

A few more inches of legroom is all i ask

Great as usual, some delays but well communicated and made up for in the air

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.
