Airline reviews

The only thing plus on this flight was the crew. They made me feel welcome and took care of me on the flights. The biggest issue is that business class always boards first on all airlines. There needs to be separate doors for business and premium class to enter. I had to wait over 40 minutes for economy to be boarded. I didn’t pay 5000 dollars to wait. The other issue not enough food choices , no sandwiches or snacks in between - what the hell. I would never travel this airline again.

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.

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; seat made ready for bed after meal, a plus since one airline covered the seat at the start.

The experience on Fiji Airways was absolutely amazing. Streamlined. All staff was amazing. Pleasant. Friendly. Extremely helpful.

Comfortable as one can get in Economy, food was very good, staff were super friendly & efficient.

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.

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

Delayed and missed connection, was not re-booked like other travelers so ended up being stuck for several hours due to no one handling my booking.

same as previous comments. i hate being on a plane that long. no problems w/anything else.

Much better than I expected for such a long flight.

Good - better than other airlines in terms of food and seat comfort.

Flight LA to Sydney was first moved earlier by 2 hrs from 10:25 pm to 8:25pm roughly a week before departure. Then on actual departure date, it was delayed 2x, and needed up leaving close to 10 pm. Then entertainment for the whole flight wasn’t working for most of the seats including ours. The baby crib at the middle isle was being taped to the wall to keep it tacked in using a packing tape while passengers were walking by looking for their seats. Not projecting good confidence. After a few minutes after take off the whole crib fell off. Good the people seating next to it wast hit or got scared. At arrival at Sydney, crew handed the customs forms as we were getting out of the plane. So passengers had to scramble to find a place to fill up the forms along the corridor going to immigration. So no one is available to help from Qantas to fill up the entry forms. Not a very good experience for a flagship carrier.

The staff at the airport could be much helpful and nicer

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

Smooth flight. As always dinner could have been more generous. Breakfast was great.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Great checkin experience and flight crew were very friendly and helpful

Staff did not care, and very clearly did not want to be serving passengers. Requests were ignored repeatedly. Toilets filthy. Bins were just trash bags hung around the place that were never emptied. It was a challenge to even get a glass of water on a 14 hour flight.

Flight was diverted to Canberra because Not enough fuel to circle on Sydney’s skies waiting for showers to pass. After that everything went wrong. It took forever to put fuel. Once back rolling, we stopped short of takeoff because crew had reached maximum work hours per shift. Back to gate we waited and waited in the plane with no water and no food - a total of 4 hours. Received contrasting news about the follow up of our trip. Finally we disembarked but our luggage could not be processed there as not enough custom agents. We ended up on buses and arrived at Sydney airports after a 3 hours trip. There we had to queue in line with 240 more passengers to file a lost luggage claim. We received the luggage after 48 hours, many of which spent holding with non-existent United customer service. Never able to speak to an actual person during those long phone calls. Finally on a chatline I could talk to a baggage agent, who filed another report as our luggage did not appear anywhere in their system. Thus it was surprising to get it back.
