They destroyed my baby’s stroller and the seats was broken

I had the worst experience I’ve ever had with any type of airline,they destroyed my baby’s baby stroller,that cost more than 2000$,the seats in a 13 hour flight was broken,so I definitely not recommend that airline for other people

The flight was delayed which cost me to missed my connection flight.

The planes are very cold. The AC is too much.

It was great honestly the cabin crew were warm and welcoming everything was perfect the food was nice.

Didn’t like anything about the flight: I am so frustrated at this point. Since 8 days I have been dealing with your customer service regarding my seat changes. I paid $51.10 for extra legroom seats and one fine morning I get an email that my seats have been changed. I tried to contact the customer service and they have been just fooling me around stating that my issue will be resolved. Saudia is the worst airline. Pathetic. On the day of my travel, I came at the counter and the guy told me that my seat assigned is 36A and my wife’s seat is different. He then changed my seats to 33A which is not at all a extra legroom seats. I asked the person is these seats are extra legroom he said yes and when I came to the aircraft I am sitting in a normal seat. The TCR Shameer Ansari or Sameeri Ansari came and did nothing telling me that he tried his best find a solution. I need someone to contact me ASAP and I need a refund for the entire flight. I don’t need your Al Fursan points they are worthless. Contact me ASAP.

I recently flew with Saudi Arabian Airlines, and it was truly an outstanding experience from start to finish. The staff were exceptionally polite, professional, and attentive throughout the journey. Check-in was smooth and well-organized, and boarding was efficient and on time. The cabin was spotless and comfortable, with plenty of legroom and a calm, welcoming atmosphere. The in-flight service was top-notch — meals were delicious and offered with generous portions, and the crew made sure every passenger was well taken care of. I also appreciated the wide range of entertainment options, including movies, music, and TV shows in multiple languages. The flight was punctual, and the overall experience reflected the airline’s strong commitment to hospitality and passenger satisfaction. Without a doubt, I’d highly recommend Saudia to anyone traveling within the region or internationally. Their service quality easily matches — and often surpasses — many top global airlines. I’m looking forward to flying with them again! ⸻ Would you like me to tailor it for a specific flight route or class (e.g., Economy, Business, Jeddah–Washington DC)? I can make it sound even more personal or detailed.

It was a disaster. The crew was so rude and had no professionalism. She dropped something onto the floor, then took it from the floor and put it into the food tray. Also, when she got some spilling, she went straight to the toilet, got some tissue and started cleaning the food trolley

I cant wait for planes to have shorter rows with more space! otherwise, all fine thankyou

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

Nice crew , clean cabin , food was delayed due to problem with the quantity .

On this flight...fine. The one from India to Abu Dahbi, awful.

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.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

excellent, staff and boarding were all seamless and no issues, thank you!

More leg space than other flights, but felt like *maybe* narrower seats?

You charged me for luggage although the airline does not- you charged me for seat when customers can pick their own seat at checkout in I travel to Europe slot and I will not use kayak again

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

Awful seating. Bad food. Staff only have one bottle of water and no cans.

it was like a banya -so hot... They did provide a great experience with special food. one toilet broke midflight In general it was a peaceful and relaxing flight - for business class it was good.

The flight from Istanbul to Karachi was an old plane in which the seats don’t even come close to lying flat. It was uncomfortable - may as well have been economy, and a far cry from Qatar Airways that I’m used to. The food was mediocre and entertainment couldn’t even be used because there was zero privacy like in a normal business class, so it would feel as though everyone is watching the movie with you - which is awkward. I had to put my food tray out as a leg stopper to get into some sort of comfortable position to curl up and sleep, which is ridiculous. Unacceptable given the ticket still has a business class price tag.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

Boeing 777 is a bad choice for a such a long flight.

It was great! Great value for the price I paid. Great crew and great food in business class

Pretty much what you'd expect for an economy flight. The crew were excellent as usual. The food was ok, but nothing special.

Staff is rude and condescending. Airline is badly managed. They take away their flimsy earphones and blankets one hour before the lading. I’ve never experienced this with any other airline. It’s a very portly managed and run airline that should be avoided.

The Senior Flight attendant was just amazing on our Flight GF 284 on 30/11/25. She was so attentive, helpful and caring not just to us but to all in our cabin.

Loading was on time and quick Not very many people

Amazing business class in a single aisle plane. Fully flat seats, pyjamas, amenity kits, all in all a really complete product. Service was good - not amazing - but they did a good job. Got a few hours sleep. Will fly with them again if I can.

They flight was without ait conetion weather was very hot

Did not have to leave plane. However found the wait tiring with nearly a full plane boarding at Male and being unable to get out of seat due to cleaners security and a full plane boarding with hand luggage. Staff were excellent despite a long and tiring flight due to stopover.

Everything about our return trip from Colombo to Manchester was excellent. Staff were brilliant all flights. Return flights on time and all staff were brilliant. The outbound journey however was marred by cancellation of Man to Bahrain flight. No information or staff assistance. Customer Service none existent. Told to make own arrangements by none interested or understanding telephone staff who said to make own hotel arrangements and be reimbursed. CS refused to reimburse hotel or lost lounge booking or taxi fees.

The boarding was late. The check-in board said boarding closed but the boarding hadn't even started. I have spine issue but not eligible for wheelchair since I can walk. But we were taken to a plane with stairs to climb. I requested support with the handcarry and was told that I shouldn't have booked this flight without wheelchair. Instead this information should be public if this plane has sky bridge or stairs. The infotainment system did not work either. And the plane was very loud with very less legroom in economy.

Very poor experience, passengers and were not social and started a troubled with other passengers and a fight erupted
