The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

My second flight wasn't better than the first one. And this is 14 hours trip, crew came out only to offer food and the choices was poor. This food choices are good for Asian people but not for westerners. The breakfast kind thing was a corn sausage really disgusting. The air-conditioned blower really blow high and cold, turn out on my arrival to feel seek, that makes the trip uncomfortable. The crew didn't not really come out during the trip to offer drinks or snacks. No fruits available. Very poor service

long flights are difficult but the crew and amenities made it a very good experience

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

Need to have space for Cary on when traveler boarding any zone

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

Most relaxing long distance flight I have been on. And I have flown on many.

It was our first time flying with China Airlines and had a very nice experience. The airline staff & crews both on the ground and air were very nice. Food on the plane was very good. Will recommend it to family and friends.

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

My ticket did not indication which group I was in for boarding; the gate attended help me

Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer

I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!

staff are super nice and effiecient! It was a very comfortable and relaxing flight

When I booked a premium economy ticket. I then had to pay $100+ to book my seat.

Didn't like on this return inbound flights (from Hong Kong to Vancouver) Outbound to the Hong Kong was good.

I did not take the flight, tried to cancel it right after I booked it, but was unable to reach anyone. I blame Kayak for this situation because they sent the booking through another company and I was unable to get anyone to talk to me about the situation. I had to just take the hit and pay for another flight through Cathay Pacific, which was wonderful. I will never use Kayak again. (I bet they don’t post this review!) I’ll just post about them on social media sites. I don’t want anyone to have to go through the hassle and expense I dealt with.

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

The flight was smooth, but there were not enough options for meals and I was given beef when I do not eat beef. The flight going was much better because we received more snacks.

This was a large plane with an upper deck. It seems like business was upstairs. If it was a US airline then I would say I sat in economy plus, but I think it was just economy. Though since ANA would not allow me to choose seats for the price it may have been plus. Lots of movies to choose from, and good service.

This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.

There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

We have had better ANA experience. The crew are friendly.

Great airline all together - triple 7 for a short flight was a plus - lots of room

Our bag was lost so that made unnecessary chaos On our trip

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Everything was fine and I have no complaints or things to note.

The economy seats are much indeed roomier. Meals needs improvement.

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

Excellent service provided the flight crew. Food and drinks were very good.
