Extra leg room was nice. The wheelchair situation getting off the plane was a disaster. No wheelchairs or porters were waiting for customers to be picked up when the plane arrive pretty much on time. After about 45 minutes of waiting on the chair service I just walked myself to the luggage claim. Aren't they supposed to know when the planes are going to arrive and land? It was messed up from thr time we landed. No wheelchairs and no porters. Finally After an hour of waiting for them to arrive I walked to the Baggage claim myself. Not a good way to return home from a great Hawaiian vacation.

The flight was so cold from Vegas to Hawaii. Everyone was so cold they put on goodies. They made us buy blankets for $13 each for 4 people. The plane was like an icebox. Now on the way back you made me pay extra so my family can sit together. Will not use you again.

The in flight speakers little touches of humor were entertaining.

The crew was quick and efficient. The flight was uneventful and arrived slightly early.

My seat was broken I couldn’t put it back I have really bad back issues , the flight was 5 hours delayed and there was a drink dude harassing the entire flight

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

Parents with kids should all be in the same area. Sounds rude but who what's to fly 6hrs with crying and bratty kids. Just my opinion.

Ok, so I didn’t have seats, so got there very early. I was first in line only to be told, listen for your name for seats. The flight was boarding before they gave me a middle seat, way after others showed up who were given more favorable treatment. Ok, so , don’t show up early and obey all the rules??? Clearly, your gate clerks did not. What gives???

Short flight but delayed. Since its a short flight no food or entertainment necessary

Business class Seats on the A350 from Nan to YVR were wonderful. The flight crew was okay but could do with better training. Toilets were clean but ran out of paper towels towards the end of the flight. The food/menu and the wine offered really needs considerable improvement. Dinner options were either Bolani, a beef sandwich (even this could be made much better), or paneer butter masala. Unfortunately, if you are not a fan of Fijian food, there isn’t much choice. Dessert was either turmeric ice cream or fruits but unfortunately, they were out of fruit! So the only option was turmeric ice cream. I’m not certain how many passengers like turmeric but I am not one of them. They need to cater to a more diverse group of people. Perhaps they need a new chef? The movies& tv shows were mostly older so I didn’t find that interesting either. It was however, fun to view the plane’s exterior cameras as we take off and land. The best thing about this flight are the business class seats.

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

Really liked the plane and business class seat. Food was ok but could be better. Service was very good.

Better connections, much better cabin crew, much cleaner cabin that Qantas, American and probably other carriers.

Better connections, much better cabin crews, much cleaner aircraft than Qantas, American and probably others.

Fiji left without me because American Airlines was too stupid to get to LAX on time. Fiji should have offered a standby on another flight but they told me tough luck. I will never fly with this company again.

The A350 aircraft business class experience was very good. Comfortable and well appointed pod, and supplemental bed pad available for sleeping. Food was very good.

Business class seats and amenities were excellent, crew very attentive. Slept well. Food good, lounge experience nice. Would fly them again. A350 aircraft excellent, very quiet.

The flight attendants were extremely friendly and helpful. Everything ran on time. I highly recommend Fiji Airways.

The experience was lovely in every respect. The crews were delightful.

The seats are too close together and are smaller than they used to be. Makes for a cramped experience.

The international flight from Sydney to Dallas had great food. I have travelled a lot over the years and this has been the most memorable in my experience so far.

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.) Lounge was crowded

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.)

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The crew were amazing - A great job. They made me feel special and valued.

Why does it have to be painful to fly long distances?

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

Everything was pretty good except for food. They need to improve on it compared to other airlines.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

I had a great flight. Everything went smoothly and the flight arrived early.

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

On time take off…US cabins look tired and need of refresh!

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.
