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

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

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

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

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.

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.

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.

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

The flight was delayed to board, then delay in landing and extremely bumpy landing.

Could have been on time and not missed my connection

Weather delayed arriving flight and even though I made the connection, my luggage did not.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

Seat was very old. Didn’t easily go up and down. Flight Attendent had issues moving the seat. Condition of the seat was ok. Parts were peeling off by the foot area. Food was ok. Ran out of the dish I wanted so got the beef. Beef filet was very tender but the sauce was a little strange. Disembarking was very easy.

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

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

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.

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

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

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

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

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 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

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

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.

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

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

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
