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.

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.

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.
