Poor food options for vegi folks n not enough food quantity. Fiji really needs to improve on it. Flight crew is very warm and respectful but don’t know how to cater towards vegi folks n items despite so many Indians staying in Fiji

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.

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...

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

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

Fiji Business Class was value for money. Would do again for a long haul flight.

Staff was very helpful, polite, efficient. Food was excellent. Business class seat very comfortable.

We recently flew on FIJI AIRLINES, what a breath of fresh air! From their customer service at the ticket counter/ Baggage check to the flight attendants on the plane! When I bought the tickets they were the least expensive too! I took a picture of one of the flight attendants scoop up a very fussy baby and walk her around the plane, to give her parents a break. I would love to submit, but don’t know how. Meals were great, also complimentary beer and wine was a pleasant surprise!

The business class seat was not very comfortable . Fortunately it was a short flight

check-in at sydney was a bit disorganized. one well-dressed woman appeared to be in charge, staring at others who were not ready and checking in passengers. one person at business class check-in, was sarcastic and only mentioned the gate assignment, no bother to mention the lounge access etc... the crew on board was stellar. so polite, helpful and respectful. the meals were great, endless beverages, and the a350 is spectacular with the seat/bed, amenity kit, television, bedding, headphones. first time flying fiji airways- honolulu- fiji-sydney, and sydney-fiji-los angeles, all in business class. their fares are much more affordable than other carriers. hopefully, one day, they will use a widebody aircraft from honolulu- fiji, since it is a nearly 7-hour flight and the 737-max 8, although comfortable, would be better with a widebody plane.

We got to experience Premium Economy from Sydney to Auckland and it was a great experience wiht Air New Zealand. The crew was friendly and helpful.

I was not even on that flight and did not even book a ticket. Kayak did a phenomenal job

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

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

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

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.

Economy was much nicer on the Air New Zealand planes.

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

Couldn’t request a vegan meal somehow but I noticed other people getting them

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

Going from Sydney to London on a single flight number was very convenient, not having to worry about changing planes. Entertainment system on A380 economy cabin is very dated. Lavatories are small. The self serve refreshments have been significantly reduced since the A380 first started.

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

The flight was delayed by 1.5 hours and most of the flights bags were not on the flight. Have also had no communication from QANTAS
