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.

Great food, wonderful staff made a long flight seem short

A bit cramped in economy and the people in front wouldn’t put their seats up during meal service, crew did not help with that and I felt they could have done more about it.

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!!

See previous comments. Didn’t take this flight because my other flight was so delayed. Ending up on two other flights as a result and was more than a day late.

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

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

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.

Wider seats would be nice. Love the wine selection. Crew is superb. Need more movie / TV selections.

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.

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

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.

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

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Well my expórtenle with Qantas it wasn’t that good KLM from Bs Aires was delay Santiago Chile Qantas QF 028 was still in the airport but the crew didn’t opened the door for me soo I lost my fly And I stuck in the airport 13 hrs waiting for next fly by Latam Arline My question is can I have my money back for business class
