Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

The app was awful. No accurate info. Paying for internet is a negative (Delta is free). The crew was very nice for the most part although you are not guaranteed to get good service. Some crew would ignore requests for things as simple as a cup of water if you were sleeping when the first serving was made. Food was great. Male crew member was exceptionally kind and responsive.

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)

Plane is new and I was upgraded to first class so all was great.

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.

Everything was excellent except for the hot cabin during the two trips. Why would you keep the cabins cool hot?

The ehole fliht went smoothly. No delays. Bur the food was not good.

Wonderful. I love ANA airlines. It's the best so far. My first pick when I travel now.

Loved that leg room was great for economy, and food was definitely better than other American airlines, great selection of movies. My mom is happy.

Just okay. Staff is accomodating especially at the check in counter and gate. Boarding was just fine. Leg room was cramped at economy. No entertainment, wifi is so-so. Cola in can given by cup, but rest of can was not given. At least give the whole can.

What I noticed is that when customers or passengers are asleep, they are no longer given food.

Flights were late on every leg of the trip. Seating was narrow and uncomfortable, and food was below average. I complained directly to the crew, and ANA, and was offered no offset or compensation.

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.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

The boarding process was good. The toilet could be better maintained.

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

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.

The boarding was stressful without paying extra for an assigned seat. The staff were helpful but the process is unacceptable.

Very comfortable and friendly staff! I love flying Hawaiian! I wish they had the screens on the back of the headrests for watching movies, but NO OTHER AIRLINE comes close to the customer service of Hawaiian air. Its worth the trade off of not having movies on the screen.

I love that every seat has a USB charger. The seats were comfortable and everyone was friendly! I can't think of anything I would improve.

Boarding was efficient and there was enough overhead space. Passengers were cooperative about helping each other out. I think folks are happy about going to Hawaii.

The new 787 was awesome! So updated and with the times! Very upstate! Hawaiian is very service oriented and you feel the Aloha!

Going to Kahalui was wonderful. Attendants were awesome. Coming home, I was bumped from the seat I originally booked. Imagine my embarrassment as I stood there knowing I booked my flight a month earlier. All in all, I didn’t allow that spoil a wonderful weekend in Maui with family.

Wonderful flight. Food and drink were given as well as wifi. Amazing luxury!

2nd flight of the day, delayed from the 1st flight being inoperable, and then this one was delayed 45 mins too.

The flight from LAX had broken AC; they deplaned and sent everyone to a gate with no agents, so I called HA to try and get rebooked. Customer service was great; I at least was not being put up in a hotel for a night this time. If I hadn’t called, well, that original flight I was on got cancelled before I landed in HON. The result was arriving over 7 hours late and missing a half day of an appointment I should have easily made even with a small delay.

Great service and crew. The food however was awful. I was ill after eating a bit of it.

Very good. Very efficient. Entertainment was not functioning both ways which was disappointing.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

My first flight left so late we knew I would miss my connection. Rather than redirecting me then, they made me take a flight to Montreal, then Toronto (there was a flight leaving for Toronto when I was in NYC, no need for me to also go to montreal). Then they gave me a food voucher that did not work (4 places would not accept it). At least they gave me a hotel automatically, even though it was a cheap crappy one. I'm still not home, and it's been over 24 hours. I'm exhausted.

Liked the size of seats. Not much food offered given length of flight.

The boarding was at a dual gate hallway and there was only one spoken explanation about which way to turn to board the correct plane. It wasn't marked visually at the split in the gate. The phone charger did not work at my seat. The temperature was quite chilly throughout the flight and the recorded announcements were extremely loud for a small plane.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!

Flight was delayed 1.5 hours as crew was stuck in traffic...that is absurd that the airline would be transfering a crew by car through NYC during rush hour. I missed my shuttle bus and got stuck in Vancouver for the night. Airline did not offer a voucher

I booked these flights for our group of 4 people several months in advance. On the departing flight, I checked in 24 hours before flight and was able to select the seats that we liked. On the return flight, I had no internet access until about 12 hours before flight, when I tried to check in, we were scattered all over the plane in middle seats which is absolutely ridiculous. I book all 4 ticket in 1 booking MONTHS in advance, the preassigned seats should be together, NOT scattered in 4 different rows in middle seats.

Very unfriendly crew, Air Canada should hire staff that are willing to do their job and be friendly to others. Unmannered flight attendants.

It was absolutely awful in every week. A mechanical failure led to a 6 hour delay, cancellation and rerouting.
