Old plane, food not that great - lacked taste. Crew was nice but strict.

Old plane, food not that great - lacked taste. Crew was nice but strict.

Flight attendants were attentive and friendly. Enjoyed the peppered shrimp snack. Check in was easy. Only negative was the time it took to get checked luggage, but that was the slowness of CPH staff.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Staff was fine. But plane offers very few free services.

Passengers need to be consistently told by the stewardesses to position their seats up from recline when eating. This is not something passengers should have to request. Common courtesy...

Got delayed, we missed our connection because of this and were stranded for hours in Los Angeles with no way to go home. Don't fly Scandinavian Airlines!!

Different airports have different regulations (weight/size) for carry-on.

Everything went very smoothly. My only complaint is how cramped the seats are for an international flight.

They were charging $$$ for first glass of wine. That first glass should be included in such a high price.

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

Not impressed. Only allowed one carry on on such a long flight.

The crew was fantastic and the over flight was perfect as well.

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

There was no phone charger, uncomfortable seats, unprofessional flight attendants, didn’t like food. Could not reserve seat in advance

In spite of placing requests for vegetarian food, I didn’t get it because they ran out of stock. According to crew, only fixed number of vegetarian orders will be carried. Typically, they should have checked and served those who had specifically requested. I was one of those to get the food last.

Ordinary Indian food... Not great. Limited movie and TV selection

Vistara i bought a biz class fare but a few days before vistara always changes my biz class flight to economy .. happened to me 4 times .. seated could be wider .. boarding could be more organized .. crew did their best but not enough resources all in all very poor experience Qatar Delhi .. only complain .. no clear signage to lounge for transferring pax .. its a Delhi shot coming.. no feeling of exclusivity for biz/ 1st class pax.. but everything else was much better .. once i boarded Qatar .. i loved it Qatar to Washington .. only complain i boarding .. too crowded .. no separate area for biz/1st class should hav completely separate area for upper class.. security is stifling pax comfort by the gate ..but everything else was great

It is an international flight so food, entertainment and blankets is minimum requirement. Also cleanliness was very poor.

The flight was mostly good, but I sat next to a couple of passengers who were semi unpleasant. We sat next to the emergency exit. One man was drunk and when he got up to get something from the overhead compartment, he tripped and fell on me while I was sleeping, waking me up. The other man seemed sick as he was sneezing a lot and clearing his throat and nose often. This made the flight a bit unpleasant unfortunately. Otherwise I’m usually very happy with QA. Thanks

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

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

Eine Toilette der Business Class war gesperrt und somit nicht benutzbar.

1.Aircraft Comfort: The aircraft type was quite small with non-reclining, cramped seats that significantly lacked comfort. 2.In-flight Entertainment: There was no provision of in-flight entertainment screens or Wi-Fi for the majority of the flight. 3.Boarding Process at New Abu Dhabi Airport: Despite the move to a new airport, which promised enhanced experiences, the use of buses instead of jet bridges did not meet expectations, causing inconvenience. 4.Gate Change Communication: A last-minute gate change was poorly communicated, resulting in a long and difficult walk.

Excellent service and great help when i traveled with broken leg

The legs room was not enough at all. The seats are not comfortable enough for long journey but other than that it was very good

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping

It was a short flight. Plenty of room on the plane. It was also extremely clean.

The crew was exceptionally polite and caring. The plane was comfortable. Great experience. Will fly more on Air India because of this experience.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.

Snow storms at Chicago Not the fault of the company But nightmare experience

No way flights should have been suggested or sold with such little time in between for multiple security checks and customs AND terminal changes. All boarding passes were not given by first airline. We had to run in Frankfurt and missed flight in Chicago.

We spent over $1,200 to upgraded to buisness class and they didnt tell us that they separated our seats and only had economy seats together. So we downgraded in order to sit together and they wouldn't give us a refund. Then when we got to Split, Croatia they had lost our baggage and we are still waiting for them to find our luggage. Now we are scrambling to find clothes to wear and necessary items in order to live. Terrible start to our vacation
