The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

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

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 were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

Always fly with Korean Airlines. Best service great food. Nice and clean as always.

Packed flight and not sure why dinner service would start at midnight while passengers we’re trying to sleep

Travelling with 2 others for work. Delta asked to check their carry ons due to the fullness of the plane. This was all good until the next leg of the flight. One of the 3 had their carry on checked through to the final destination but their passport on in their checked bag. Which they could not get to and he was not allowed on to the plane. Even though Delta had to retrieve his bag, because he was not allowed on. So they got his bag and he was in the terminal, but even when the flight was delayed, due to mechanical issues, he was not allowed to come onto the plane. Since the delay was nearly 2 hours, he was finally allowed back on the plane.

Boarding was delayed by an hour and then we proceeded to sit on the tarmac for another 30-40 minutes. No clear explanation was ever given and the delay caused me to miss my connecting flight home. Was forced to stay the night in the connecting city which impacted my following workday and cause personal issues at home as well.

Good flight — left on time due to on time arrival of Pittsburgh flight

Delta keep on impressing me. Right now Delta airline is the best of them all

Good but since we got in early we had to wait on runway for our gate. That was kind of a bummer but we still got in earlier than planned For entertainment I was watching a movie and getting close to the end of it with 15 min left but it kept jumping automatically to the next movie before finishing.

13 hour delay stuck in Detroit and missed a day of meetings. It was terrible

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

The cabin was definitely dated, but that's about par for the course. The flight crew were wonderful as always (always a Delta highlight), but the boarding process was slow with little direction or encouragement to get people in their seats quickly since we were already delayed.

Totally organized, quick boarding, professional staff and ON TIME! Good size seats in the cabin Wonderful experience

Great flight. I should have figured out the bed situation in biz class earlier. Confusing in dark. My bad.

Business class check-in was flawless; was automatically given a lounge voucher. Flight attendants were helpful and professional. There was a purser who introduced herself at the beginning of the flight but then I never saw her again.

For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

Simplicity of boarding and corporate interactions were all totally positive and simple, brief, organized and clear. No regrets at all. I will favor flights with Cathay Pacific in the future.

Big selection and great food and beverages in business class with good service. Full recline but less privacy compared with Qatar.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

From BOS to HK, the crew had pushed me to choose the pasta for meal multiple times. It was a bad experience. Without this, everything was good.

The overall flight went well and the aircrew was pleasant.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Ultimate customer care humble and excellent service oriented crew , perfect timing maintained by the crew . My profound appreciation.

Only negative was dostancevto transfer in Doha with no big golf carts to help us. Walked over 2 miles.

My Tv don’t work the whole from Doha to New Delhi. Overnight didn’t work from Bos to Doha and had to eat food without light

Everything from start to end was good and easy plus clean i enjoy my trip in qatar airline

No boarding passes given at start point Too much wait for boarding passes

Flight delayed, rerouted, communication extremely poor. Crew efficient but robotic, not supportive

They over booked the flight from Abu Dhabi and put me on a flight 2 days later. Unbelievable experience even after booking business

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..

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.
