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.

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.

The airline is ok, but it needs to improve it schedules.

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.

Very clean aircraft. Friendly staff. New plane. Food quality was good. Not my flavor but I saw the effort.

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

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

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.

It was ok, but not what it was like 20 years ago

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.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

Loved the food and beverages available, spacious economy class, excellent entertainment

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
