The flight was just ok, but the vendor made it exceptio ally bard to manage my own reservation and would not give me access. The blocked all of the one time pins to come to their email address which caused me.to go through them eceryrime to get seats see rhe reservation and even get wheelchair access for my sick 71 year old uncle. They only xommunicates via a bot which gave me incorrect info. I thought this was Kayak and not underprivileged. They ruined his trip, did not get him aisle seats and made it impossible to purchase extra leg room. It was a horrible experience. He was taken to hospital on arrival only to find he had blood clots and pnemonia while trying to navigate the airport. This vendor is very irresponsible and the airline could not access his info.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

Overall, not good. Super late boarding in Hong Kong because some last minute issue with a plane. The boarding process is chaotic. Kathy Pacific should seek to do better with punctual departure time. Caused a lot of trouble with missed connecting flight.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

First time tying out business class with this airline, hat a disappointment, never returning. We didn’t get the meal as requested from Singapore to HKG flight. While meals served connecting flight, crew takes meal order based off passenger membership status by giving the. Priority selection of meals. It was a battle, plain disappointment, not worth the hype, price, class as categorized/ advertised

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

Close to excellent. The only problem is when I try to charge my phone on the USB in front of my seat, the battery level is decreasing rather than increasing. Why?

A lot of things Never flying with this airline again Had an emergency landing

They downgraded me from premium economy to regular economy and me had 2 major lay over and had to have an emergency landing due to engine failure mid flight Don’t use them worst experience I have ever had still dealing with the trauma

The only problem was my connecting flight to Chiang Mai on Hong Kong express that I booked through Cathay Pacific was canceled and I was never told about it. I was rescheduled on a flight 10 hours later. Very long day at rgr airport in Hing Kong after a 13 hour flight but that's OK, I understand things change but I think I should have been told. I would have prepared myself for a long wait. Great flights all around though. Thank you

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

Very efficient and professional staff. Food was good and so was entertainment selection.

As good as you can expect an economy flight from Europe to Australia to be. Nothing agains Qatar, just feels like every new generation of plane gets tighter.

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

My flight was delayed. I was rebooked twice and even the second flight that was additional connection in London was delayed too, so I ended up spending more than 24 hours flying between four different countries and to be honest I’m not sure whether I ever want to use this airline again. My luggage is still delete. It’s been more than 48 hours now so to be honest, I’m not even sure how to describe the level of frustration I have.

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

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

They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Damage lagguage, They lost the stroller and car seat which they found after 4 days, and on the way back they damaged the stroller.

Same situation saudi lost my pram and car seat and damaged lagguage

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very bad

1 hour flight. No complaints. Some drinks would have been nice.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

excellent, the staff was kind and the boarding process was with no issues or hassle

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

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

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

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

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

Stewardess was attentive and was actively roamin to check the passengers on the biz class

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!
