AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Lousy entertainment system. Crews are excellent. Meal is just mediocre.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

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

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

Excellent service, love the extra amenities (water bottles, blankets, etc.).

They had the same movie choice as my previous flight, not much of a choice, movies were not up to date, music was uninteresting. Other than sitting on the ground for 40 minutes after boarding the plane, with pilot telling us that they couldn't load the plane because of rain, (bullshit) We finally got into Bangkok of course 40 minutes late.

After the gauntlet of unnecessary security, and the two mile jog to make the flight, the flight was delayed 20 minutes on the ground for takeoff.. However, once in the air, the crew gave its usual excellent service.

I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

One of the business class panels where we were sitting was broken and it didn’t close. Therefore, the be privacy was limited.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Service is great. Seat is ok. Not much storage room and seat is hard but seat topper was nice. Cabin was very warm most of the flight. Washoku Food was good.

Gate agent and flight attendants were efficient, but more stern than warm.

Two of the flight attendants were cranky and seemed like they didn’t want to be there. Not up to normal Delta standards. And our bags didn’t make flight to Italy from Amsterdam resulting in having to make a trip back to airport which cost me 75 euros.

Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

I just can’t understand why are you sell to many tickets ???? We had to wait 2 hours before 13 people from our flight take money and go to next day flight!

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

Wifi is very frustrating - could not connect and therefore unable to work on the trip

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

Staff members were not helpful they ignored all calls for an attendant.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Is ANA airlines not united airlines, ANA airlines crew working professionally , more services providing, happy face to service customer

The first segment from Atlanta to Abu Dhabi was fantastic, but we got downgraded to a different aircraft from Abu Dhabi to Delhi. We were supposed to be on a flatbed business class when we booked it but just about one week before travel, we were changed to A321 Neo, which just has old-fashioned business class seats that recline but don’t go flat. While I fully understand that sometimes these changes have to be made for operational reasons, but I asked for some credit or compensation for that and I did not get any anywhere with that

Luggage jandling sucks. I arrived in BLR india on 15th and luggage was delivered today 19th. I came for a business trip everything got screwed up. Poor communication. APP kept saying mishandles in BLR. It never reached BLR. I had air tag which showed luggage was in Germany. I could not reach anybody other than the airpprt people. They had no clue and asked me to call etihad. In India etihad number wasnt working.i had to call US number and that person was the only person who seemed to help. They kept me in dark. No communication or email till i spoke to the person in US.i have flown many airlines but never had this experience. For me this was first and will be last in etihad. Very bad.

Awful , hidden charges for the luggage was a very awful thing, very much a scam , booking the flight thinking the luggage was included was definitely a scam , then the girl that was taking my luggage Ayrlease the airport was an absolute awful , telling me if I don’t have money to take my luggage with me I can just throw it away , how professional, NEVER AGAIN .

Connection booked by Etihad was delayed and upon arrival to counter they closed it and denied boarding although there was still 15 minutes to go . Manager Karen was very rude and did not want to listen seems there as overbooking and canceling boarding was the only solution..

Doubled charged me for luggage and lost $520, dug much into my travel budget.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Same problem place in the middle so small Im 1,85 m so not good 👍

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight
