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...

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.

Food choices perhaps not the best. Only offered beer and wine, when it appeared other liquor was available. Entertainment wasn’t so good.

Not a comfortable trip, the seats are not good, and they look old.

Lost my luggage and brought someone else luggage to my airport.

Not entirely positive. It’s frustrating that everything is done through the united app. One of our flight attendants on our trip from San Francisco to MSP continually had trouble hearing people so she flipped her hair into people’s faces

Our original flight was cancelled from SFO to AKL on 6/16/25. So we had to stay overnight at a hotel after a 12-hour layover plus 3-hour delay before the cancellation. Then had to fly to LA and then to AKL the following day losing an entire day of our vacation in NZ, that we can never get back.

Full flight. Flight attendants were harried. Otherwise, fine for the typical cramped seating conditions in coach.

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

The 10hr flight was a comfortable as it could be in row 57. The food was just very bad….bland and soggy!

The business class upgrade meant a good sleep on the way home after a long week away. Excellent service, great food, and comfortable seat/bed for the journey.

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

The issue was with getting our boarding pases. There were issues with our arrangements that were made through Kayak. I am sorry to say that we will not use you again because of this. The flight itself was good and the flight attendants excellent.

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.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

One of the oldest most uncomfortable "lay down" seats I've ever experienced. Old plane and old seats that don't lay flat. The seat back does not even recline - at all. Instead the legrest awkwardly extends to fill the gap between a small cubby into which you must insert your feet/legs. I am 5' 11" and could not lay straight but had to tuck my knees. Ticket was also very expensive. Would not recommend flying business/first on Finair from Melbourne to Bangkok and will not do so again myself.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.
