Good experience but could be better for people with injuries and needing extra assistance

It was a good flight. I would highly recommend it to family and friends.

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)

On time service. Seat comfort and the crew service very good .

Only one Hindi movie from LAvto Taipei and same movie from Taipei to Singapore Really horrible and we call it entertainment???

Food was ok. Could have been better. Entertainment was limited, especially for kids.

The crew was very helpful. Food was prepared with great care and tasted wonderful. Movie selection was a bit limited. The bedding on the seat is a little too thin for sleeping.

• Crew obviously hate their job • We were placed in the very back of the airplane even though we checked in 4+hrs before our flight • We were given food but since we were in the back of the plane, we were rushed to throw it away. • This was the most unorganized boarding experience. They just called “Group 1” to board and after that, it was chaos. Everyone was confused and they only spoke in Chinese.

Their announcement was not quite clear in Chinese. The rest is pretty good.

I have never been a big fan of airplane meals

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Flight was overall OK: lovely staff and smooth travelling. The only downside was no food was available on a 3.5 hour flight over lunchtime. Luckily we had realised this in advance and brought our own bento.

The whole flight in Economy was great, the crew were just amazing and the food was great as well

Crew went out of their way for me, not often

Lots of legroom for a small flight. There was in flight entertainment even though it is a short duration. We waited on one passenger to board for a long time after everyone else was on.

Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Easy if you are a United States Citizen, when you go to US Border & Customs, bring your Passport if you arrive Internationally. Remember to pick up your check baggage before moving into domestic flights, as they will check the tag for the plane you are boarding in. (They will check your baggage again). Bring your ID/DL (Real-ID COMPLIANT) with you to pass security/TSA, passport works too. SFO is pretty strict as well as LAX. Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

At Fukuoka, check in counter stuff was no experience , took long time and took out our preserved sheets to change to emergency exit seats without asking. The flight was late and we missed the flight to go back to SF. My luggage was broken. I had a terrible experience.

As my first experience in business class it was a great trip considering how long the flight is and how hard it usually is to sleep in economy

Great service. They could offer vegetarian food and do more to reduce waste.

I like the food, the crew and everything.!!! Except for the delay in our flight.

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

The staffs are very accomodating!!! The foods are good!!! The entertainment from manila to incheon was miserable because we need to use our own cellphones or own ipads.

Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️

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.

Very comfortable seats, delicious meals, and friendly and helpful staff

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

I recently had the pleasure of flying with Asiana Airlines, and I can confidently say it was an outstanding experience. From the moment I checked in, the staff demonstrated exceptional professionalism and warmth. The boarding process was seamless and well-organized, ensuring a stress-free start to my journey. Onboard, the flight attendants were attentive, courteous, and went above and beyond to cater to passengers' needs. The seats were comfortable, with ample legroom, and the in-flight entertainment options were diverse and up-to-date, making the flight enjoyable and relaxing. Additionally, the meals served were delicious and well-presented, reflecting a high standard of culinary quality. The airline's commitment to safety was evident throughout the flight, with clear announcements and a reassuring presence from the crew. Overall, Asiana Airlines provided a top-tier travel experience, and I would highly recommend them to anyone seeking comfort, quality service, and a memorable journey.

I’m glad to comeback after 7 years. Flight from LAX-ICN was excellent

great experience, excelent aircraft, crew, services onboard a dream come true

The check in women was very nasty attitude to the passengers from Lihue airport flight 68

First time in a long time and look forward to many more

We are a family of three, bought two economic tickets for me and my teenager daughter, a business ticket for my elderly mum who doesn’t speak much ENGLISH. During the flight my teenager walked up the plane wanting to chat with her grandma, stayed a bit and my mum consequently wanted to exercise so she walked down to our cabin too. My mum sat with me and chatted for about fifteen minutes then i went to business to check on my daughter only to find out she was not there. I was met with this extremely rude Hawaii Air flight attendant, after i told her my daughter is missing she couldn’t care less, she told me we can’t swap seats and insisted that i immediately return to the economy cabin. But then my daughter was still no where to be found! i explained and hoped that they could at least suggest some way to find her such as announcement or something, but the following words came out of her filthy mouth: “ Go back to your seat immediately! this is the last warning!” WTF?! i can’t believe this is the way Hawaii airline is treating their passengers and we paid business class fees! Very insufficient and incapable flight services as well by the whole crew. Overall extremely unpleasant flight experience! i will definitely spread words about this to ALL my family and friends and colleagues you name it. Never fly Hawaii Air ever again! Never!

Allowing passengers to move to empty seats if flight isn't full.

Enjoyed every stage of travel and really loved the free WiFi on the international flight. I would only make one recommendation. There was a lot of young children under 2 on the flight. Loud crying screaming and just playing. Constant poopie diapers. These families were spread through out the plane. Some of the passengers with no patience actually yelled at these parents unfortunately. I would recommend keeping all the families with young children in the same part of the plane if possible that way the passengers that complain can be relocated. In this situation there was no part of the plane that didn't have a noisy child. Any ways I will be flying Hawaiian airlines again because the service was just that good!

It was a 48 min flt......so no real comments can. E made

The food wasn’t very good but everyone on the plane was great.

Friendly crew, flight left on time and arrived early. Had problems with using in flight entertainment on my iPhone, could not get it to work, with WiFi available. Liked being able to charge my phone. Overall a good experience!

The plane was nearly empty. My wife and I were seated behind a family with 3 sreaming kids. The parents refused to control their kids. When we tried to move to a quieter section of the near-empty plane, the flight attendant said please return to your seat. When we tried to explain, he stared at us coldly and simply repeated please return to your seat. When I asked if we could move after take-off he simply start and repeated please return to your seats. About as far from friendly and helpful as you can imagine.

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.
