Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

They were helpful, considerate with asking us for standby preboarding with our infant, gave us toys and excellent service onboard. They were always on time, even early boarding once! All our luggage arrived intact, and they even brought our baby car seat to oversized for us. We love China Airlines!

Better training to have qualified crews and services. My flight was from around 12 midnight Friday Taipei to Vancouver. After two hours first meal (2:00 Am -8:00 ) no crew available for even asking for some water. I was even willing to pay for water. For breakfast after 8 hours the only drink was tea and coffee no water or juice.

3 of the 4 flights had delays despite the weather being fine, but still managed to make all connections

Ask flight attendant for water during flight and she was a little rude get the water.

Flight was delay almost 2 hours from Hong Kong to Taipei. Last minute gate change from 24 to 66. Long way walk. We need to run in the Taipei airport to catch our next flight from Taipei to Vancouver. That is so suck!

For a long-haul flight, the crew did a very good job of keeping the lavatories clean and the aisles clear.

The check-in crew at SF did not put on breakable glass stickers on check-in baggages which caused my antique whisky bottle to break during transportation.

My BIG complaint was that my second flight was also delayed. That's very aggravating after traveling for 18 hours already.

This form doesn’t work. Can’t type in, had to copy-paste. The crew constantly telling everyone about minor things is unnecessary. Did you put the belt on, push your bag more under the seat… The seat space was good for tall people, the food was decent for airplane.

Roomy seats for the given price! I couldn’t ask more!

Great airline, but there was no English entertainment (movies or shows)

Check-in was an absolute disaster, taking more than an hour and half because they offered no online check-in and Kiosks were not available to use. In-flight entertainment was exclusively Korean media with a selection of only 5 or 6 movies to choose from. Korean television shows were also available. The food was lackluster. My chicken and tomatoes had 3 small pieces of chicken next to a mountain of soggy wedge potato fries. The seats were more comfortable than other airlines I’ve flown with and the staff aboard was extremely pleasant and helpful.

One of our luggage items was damaged during our flight to Newark from Incheon. Although our email communication was not responded to, when discussing the matter with the staff at the Newark checkin before our return flight to Incheon, we were provided with a free replacement luggage item. This customer service was, overall, very satisfactory.

I would have enjoyed some hot tea, preferably green tea, but they only serve hot coffee.

10 Hours delay on departure of the return flight and in-flight Wi-Fi was not available entire flying time all that caused monetary loss to my business.

Some favorite food ran out of service and I have to eat what was left available. Also I had to drink cold red wind! Why could not have been kept in room temperature?

It was a good flight, with great crew and service. I will definitely fly with them again. Excellent experience and very friendly. Excellent value.

Crew members are very friendly. Airplane is very clean and organized. Nothing can be better then now•• Thanks Air Premia

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

I guess they don’t serve drinks on planes anymore

Terrible. Unfriendly, couldn’t care less crew. Left lights on entire time for 10 hour flight Departed at 5pm local time. Captain made one announcement entire time. No information given and clearly not interested in letting anyone sleep with lights up. Food served was poor. Entertainment was poor. No WiFi choices on screen backs was dated and cheap. Seats and amenities were dated and barren. Hawaiian used to get by on their service/aloha, but that’s been out the window. Even for local interisland I fly only southwest as they are far superior. Very disappoint in Hawaiian and this flight.

Seats on second leg from Hawaii to Tokyo would not recline. 9 hrs is long in total upright position.

Apparently the computer systems were down, so I wasn’t able to check in 24 hours in advance, despite multiple times on the app, the website, and by calling. Then I arrived at the airport and wasn’t assigned a seat right away. I had to wait until I was at the gate and waited about another hour for an agent. She was nice to give me a “free upgrade.“.

One hour delay. No Wi-Fi. Old aircraft. Nasty food

The crew worked to help us find standby seats and we were able to arrive at our destination early which was great. Only drawback is airport at Kona which is in need of update - waiting at gate passengers exposed to jet fumes, there’s only one restaurant with minimal choices, etc

Increased effort to keep family members (purchasing multiple tickets in the same transaction) sitting together. Additionally, when faced with choosing seats at the automated check-in kiosk, only exit row seats charging an additional $9 were available, but if you decline to choose seats, it picks seats that are NOT exit row. How does that work, Hawaiian?

It was wonderful. I have never flown Hawaiian Airlines, but I would definitely do it again. They were wonderful.

Our first experienced in Hawaiian Airlines was just okay. I traveled with my 2 year old and 5 year old and both kids are first time in Kona. We had delayed in San Francisco for 3 hours which is okay safety first. Originally our flight from sfo to maui to Kona since we had delayed the airlines re-route us from sfo to maui to Honolulu to Kona. I don’t know what to do I felt bad with my two kids they have been in 4 Airports and 4 airplanes going to Kona. I cried after we checked in at the courtyard Kona. It was a lot for my 2 year old and 5 year. Like I said I know it is safety first but the Airlines could have done better for people that traveling with kids. If you are in my shoes all what will you do? Anyhow, I tried to make my two kids as happy as possible while we are in Kona. I am not certain to fly Hawaiian Airlines again. I hope my experienced helps to improve whatever it needs to improve With all due respect, Christina Lorenzo

Nice. The chairs were a little uncomfortable. And the sound from the earbuds I purchased on the airplane didn’t work very well. Other than that it was a great flight… oh and the snack could have been better… a bag of peanuts would have been better.

Our flight to Lihue was cancelled two times so after paying for baggage etc we had to go to seattle wait a couple of hours and then to Lihue. What should have been a five hour trip took over 10 with two kids and four adults, frankly it wasn't fun. The trip home was ok but seats are very cramped . I just wish we could have spoken to somebody who would understand what a hardship this was on our family vacation
