The food was not that good. I liked the miso, green tea, and ice cream. I wasn’t able to put my carry on bag under the seat in front of me. The flight was smooth. Please expand your choices of movies especially the new ones. I can’t choose any of those films. They’re old.

The food was not that good. I liked the miso, green tea, and ice cream. I wasn’t able to put my carry on bag under the seat in front of me. The flight was smooth. Please expand your choices of movies especially the new ones. I can’t choose any of those films. They’re old.

I like the braised beef., miso soup,, and green tea. Very little choices of hollywood movies. The PA announcement in English was not very clear and very soft. I could hardly hear.

More updated movies & Chinese movies. The food sometimes overcooked. Prefer to have more neat snacks in between than just choose from the menu. Please change the menu every now and then. This is my second time flying within one year and the menu didn’t change at all!

Food is lagging. Very poor choice. Like vending machine fast food.

Please change the menu more often. The beef is not tender, more choice in ice cream flavor. Dessert is not good too.

The Experience was fantastic, it's a quick flight so no entertainment or food. Just a refreshment

Great crew, Japanese domestic flight is just a drink service but crew are very attentive

Again I paid for an upgrade on my credit card didn’t get it need a refund. . American I not good at gettin in contact for refunds.

l enjoyed the variety of good and drink choices. The flight attendants were very quick and efficient to our needs.

-Bathrooms were regularly checked/maintained. -Food was okay, but the miso soup was good. -Top of my foot got bitten by a bug when I took off my shoes and was only wearing my socks. It was swollen and very itchy for several days.

Very smooth flight, great landing- entertainment didn’t work so well

Pilot and first officer did really an amazing job. I can best discribe their flying as finesse. Inital service with food/beverages was great, however after that the crew just kind of packed it in and were sitting in the galleys chatting for the remainder of the flight. I wanted a bottle of water, went to the mid plane galley, was told they were only available in the back, so had to walk the length of the plane just to get a bottle of water. That was a new experience on an airplane for me. Pretty sure evem Spirit will bring you the bottle of water you are paying for. Seat was comfy, magazine worth the read. Entertainment nonexistant unless you want to pop for the $4 headphones.

When I got into Maui I had a layover but there was a flight to Honolulu earlier. I asked the gate agent to see if I could get on the earlier flight to get home sooner. Ke'van is so great! He was very helpful and friendly and I appreciate him very much

Unable to perform online check in using Hawaiian Airlines APP Only ONE meal choice available - Totally unacceptable Low Airline ranking compared to other International airlines and service Old Airplane (A330-200) Entertainment system - Outdated Total Score - Mediocre

This flight was delayed approximately 4 hours due to bad weather in HNL.

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

Flight delayed then cancelled then gate changed two times then baggage lost.

My flight was canceled minutes before boarding started. It took three hours to get rebooked and it was on another airline overnight with another stop added. All I got was two $15 food coupons.

The plane is extremely loud and there’s no place to charge devices.

The overall flight went well and the aircrew was pleasant.

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

The boarding experience was as expected and went well. The plane's economy seating plan is not designed for a positive customer experience but rather for company profit. When the passenger in front of me reclined, the distance from the screen to my face was the span of my hand (thumb tip to pinky fingertip). There is no such thing as personal space in this setting. This results in the domino effect, for when I recline the person in back of me reclines and so it goes. This is not to say that reclining is the answer as the experience is not increased, but simply managed.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Very poor check-in experience, and flight meal service was very disappointing with no drinks service or hot meal.

Not impressed with check in desk staff at Vancouver airport. Not a professional mind service and not cared or tried to help. Don’t think I would fly with them again

Seats were very comfortable. Crew were excellent. Food very good.

They canceled the flight on us very close to the flight date .

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

It was delayed but got us to YYZ. I had great copassengers.

Flew SEA-CA, then CA-NRT. First flight was short but very uncomfortable, dirty, and had very small overhead storage space. The seats and fans were not cleaned and had visible dirt on them. Second flight was perfect.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

Everything went smoothly and as expected. We were on time and one flight arrived early.

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

All was good, except our baggage was lost for most of a day. We are thankful that it was found quickly and delivered to our hotel. Rouge was fine outside of that problem.

Everything could be better. The plain was in Orlando for 3 hours prior to boarding. After boarding all the passengers they found out that plane has a mechanical problem. After an hour the problem was solved, the pilot comes on and states, (We have to go back to the gate and take on more fuel!) Are you kidding me???? Who they have for pilots, Boy scouts?? I barely made my connecting flight to Vienna, but my suitcase did not. I'm still waiting for it, in Gyor, Hungary. Am I having fun yet?? Other passenger were in the same binned. I travelled all over the world both for business and pleasure with all types of airlines. By far of all the carriers I travelled with, Discover is the worst. I'm contemplating to bight the bullet and go back to the US with a different carrier. For International flights, the seats are made for little people. The person in front of me had his seat reclined the whole way, I felt like he was sitting in my lap. For closing, I would not let my dog travel with Discover, yet alone recommend it to an other person. Does it sound like I'm frustrated, Think about having to travel back to the US with them. I'm sure I'll not hear back from you, because nobody wants to hear about bad news, but with all the hype Discover puts out there about their services, nothing could be further from the truth.

Only problem we experienced was not anything to do with Lufthansa. When changing planes in Frankfurt we spent over an hour on passport control line. Lufthansa did a marvelous job on everything from keeping me informed via texts, to terrific cabin crew.

Bordón could be bettet if the company say before boarding the order of the different groups.

Checked in is easy and it was a smooth flight from LAX to Munich

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

The Lufthansa part was wonderful. The short connection flight was not.

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

It was a busy flight and all the crew were very helpful and gracious
