Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

Great service and comfortable seats. The first meal was excellent but the second meal was only satisfactory

My favorite airline to fly across the Pacific. The Business class lounge is fantastic, the wonderful flight attendants are helpful and professional. Great comfort while flying.

The flight was delayed for 2 hours, however, we flew home safely.

Seems like crew assumed you're korean. Not impressed by crew

Staff was excellent. Food could use more variety. -More vegetable options. Menu didn't have juice or soda listed. -The croissants were outstanding!

I had the most wonderful experience from CEB bag drop through deplaning. The staff, the aircraft, food, and cabin crew were all amazing. I want to give a kudos to Marky from Mactan Cebu's Asiana airport staff for his exceptional customer service and assistance.

FA were very great, plane was A350 new and clean

Great food, wonderful staff made a long flight seem short

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!!

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

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.

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

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

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.

It was a good experience except that the flight has been rescheduled, bit disappointed but it happens.

The flight attendants were very helpful, efficient and courteous in helping everyone!

I love the comfortable business class seats. The service was excellent. Staff was friendly.

The staff were so friendly and accommodating. The food was great. Lots of movies to choose from as well as tv shows. Highly recommend.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

If I had blood clots, that window seat would've killed me for certain.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

We requested special assistance and Cathay Pacific provided it in Sydney, but we were completely forgotten about in Hong Kong - when we really needed the help to catch our connecting flight. Really disappointing service.

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

No internet on flight, which makes log travels really hard.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

Fine and uneventful I got to my destination safely No inflight entertainment Seats are not very comfortable

The flight attendants were not very nice. No smiles On my return trip I was charged for one bag $83.30 although I had purchased the flight including one piece of luggage. Can this be refunded to me? Thank you!

Full compliments to Captain for all four landing. Crew could be more polite and nice.

So smooth and easy! From boarding to arriving, we are very happy with our experience on air Canada.

There was a long delay on tarmac. The pilot kept us informed. The flight stewards were not entertaining or comforting. During the flight we received minimal service. Several food choices for purchase were not available at our seating of row 52. Only twice were we offered water for hydration. A half hour before landing teh pilot acknowledged that some passengers with connecting flights should tell flight stewards and they would help.. We had a connecting flight thand at should have had a 2+ hour layover and now would be less than 1 hour from departure. The flight attendant told us not to worry.. plenty of time. We did not get off the plane until after 6 o'clock. We are seniors (ages 74 and 72 ) and had to walk the length of the terminal to go thru customs and the length of the next terminal to departure gate for 6:30 a boarding call. We ran and were breathing hard and reached the departure gate by 6:50. We rate the flight stewards negatively...the pilot did his best.

It was very bad travelling with air canada the people working at check in bagages was very bad person any way I pay to much many to get good flights but it’s not

Air Canada switched my connecting flight to Alaska airlines without any communication to me. The process of finding this out, needing to leave one portion of the airport for the next and what i should have done with my luggage was not communicated to me at all. Even the Air Canada agent that noticed the airline switch at the terminal did not explain this process to me. In doing so my luggage did not arrive with me. The delay to create a claim too 2 hours.

Food was great. Staff was great. I would have liked to see more in flight shopping - they went by so fast I missed it. I would have liked more variety in tv shows but overall flight was great. The staff made all the difference.

The bathroom I used could have been cleaner and tidier. Didn't look like it was kept very well. The staff were super helpful. There was an issue with my screen, and they rebooted it for me. They were also great at dishing out our meals, and cleaning up after.

The seats were very nice. The flight attendants were obnoxious and rude. I felt that if I asked for something they would bite my head off! When I did ask for something, they said they would do it after they finished what they were doing, but never did. Horrible. Check in at business class took way too long.
