This is not what I paid 6000 dollars for this seems like a joke. The lounge was pitiful with one shower for 100s of women. The food was scarce at best. There was curry, pasta and beef. What if someone was on a diet and allergic to stuff in the curry? I couldn’t eat anything there. I really would like a refund even a partial refund.

Everything was great . Arrived on time was smooth plane was clean. Crew/Staff was friendly and helpful.

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...

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.

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

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

1.5Hrs to get from plane into terminal. Long wait. Flight to NZ 1 he late

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.

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

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

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.

Was disappointed that we couldn't use our lounge passes as the booking was a group booking.

I think it is much better than the flight I flew from Sydney to Tokyo.

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

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 !

We had a medical emergency, needing to get to an emergency room upon landing at LAX. I let the back flight attendants know the situation. One, David, contacted the pilot, who made arrangements for EMT's to be there when we got off the plane. They went above and beyond for us. We didn't have to go through customs, as a customs person came to us and checked us right at the exit of the jet way. Another wonderful woman, a United employee at LAX, perhaps a customer service liaison, took care of our luggage situation, as we weren't going to make our connection to Bozeman. When we came back to LAX to see when we could get a flight to Bozeman, the personnel are very accommodating and booked us on the next flight out, and assigned good seats. It was a horrible flight, physically, from Sydney to LAX, , but the professionalism of all involved was excellent! We are very grateful fir the way they all stepped in and helped during a very unpleasant medical situation. Thank you!!

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.
