Airline reviews

I purchased my two tickets on February 2025. Tickets were by each other, aisle and window. However, when we were boarded the assigned seats were one by the window and the other one in the middle of the four seated row. It was a horrible experience and we had to tolerate 17 hours of flight seating by different people. If the airline changes the seat arrangement, it should have the decency to notify the passengers in advance. I have checked my return tickets to Los Angeles, and I have noticed that they are not by each other and I don’t know what to do. I hope someone contacts me and rectify this mistake.

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

The friendliness of the attendants, and the quality of the service.

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

toilets could be cleaned more frequently, everything else was pretty good.

The seats were more narrow than at other lines. Food was mediocre (economy class)

I was traveling with my 3 minor children, one leg I was seated two aisles behind them. On the longest leg I would have preferred sitting across the aisle from them, not behind. My youngest is 4yos. I understand airplane seating configurations are not the airlines problem but seating the one adult with a reservation apart from the minors was very difficult.

Left hr late & arrived 1hr late luggage was slow to be offloaded! The flight crew & food were good! Movie selection was ok!

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.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

The crew and the food were excellent. The plane was kept quite clean.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

The taxi drivers are very rude. Didn’t wait. They said you come in 5minutes or I leave. Did not leave any messages on front desk and they left. We have to hire new cabs in turkey.

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Bough tickets with luggage, but made me pay at Airport as well

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

I enjoy flying with Turkish Airlines and such good hospitality among the crew memebers

I did not like the quality of the food and there was no snacks offered between meals.

A little bit more comfort. It’s tight space around the seats. But all else is great and a smooth flight!

Total chaos with baggage check in…..rude staff in Seattle. And faulty seating/entertainment systems. Unable to log in to WiFi desperate being a member. Kept on getting errors. Never again. Definitely not what’s expected from a Star Alliance member airline.

As far as I remember I've selected and payed 65$ for a seat on the aisle. The seat selection got lost and the location was bad.

Qatar Airways has consistently set a standard in my mind that very few airlines manage to sustain, and once again, this journey in Economy Class lived up to that expectation. As an avid globetrotter who travels extensively for work, I experience many airlines, service cultures, and levels of hospitality. Yet there is something reassuringly consistent about Qatar Airways. It is not simply the onboard service, but the entire experience: the professionalism, courtesy, warmth, attentiveness, and genuine sense of hospitality. The cabin crew are exceptionally well trained, composed, aligned, and polished in their delivery, yet their interactions rarely feel mechanical. They remain remarkably courteous while retaining a genuine human warmth and an apparent eagerness to assist. On almost every Qatar journey, there are individual crew members who somehow manage to stand out and make the experience even more memorable. What I value most is the consistency. Qatar Airways has established a certain benchmark of expectation for me and, over many journeys, has never underdelivered against it. There is a sense of confidence and ease that comes with boarding a Qatar flight because I know the overall experience will be thoughtfully delivered. For someone who spends a considerable amount of time travelling, that peace of mind matters enormously. Qatar Airways remains one of the airlines I genuinely enjoy flying, not because of any single aspect of the service, but because of the complete package and the remarkable consistency with which it is delivered. The only disappointment on this occasion was that my luggage did not arrive with me at my final destination in Kolkata (CCU), following my journey from Seattle (SEA) via Doha (DOH). Unfortunately, the baggage was delayed in Doha. A baggage exception report is already on file with the local airport team in CCU. Given the confidence Qatar Airways has built with me over the years, I remain optimistic that they will once again live up to that expectation, work their magic, and reunite me with my luggage within the next 24 hours. Looking forward to a swift resolution and, notwithstanding this final hiccup, another thoroughly enjoyable Qatar Airways journey.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

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.

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

You're like a poor man's Emirates Airlines. The Asian vegetarian food was awful. The entertainment selection was very limited and not contemporary at all. The seats were cramped. There was no plug for charging my phone (I refuse to plug into a USB port - A security risk). The plane itself was aged.

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

Qatar screwed up by delaying our onward journey for refueling, which resulted in missing our connecting flight to India. the airport qater staff at Doha, herded us like cattle in a very incohesive and uncoordinated way. We were then given 2 options: either catch our original flight the Next day ( After 24.hrs) or catch 2 flights instead , to goto our destination in India. All this, for paying a premium for Qatar.

This flight was packed and undercrewd! Service cart cam by twice on a 14 hour flight

We encountered a glitch when we tried to board the flight because our boarding passes had been printed by Qatar Airways in Jakarta. Those were not recognized by Alaska’s system also we had to step out of line and have new boarding passes printed.

Flight changed to Oman air under one alliance . Seating , entertainment was not up to the quality of QR . Hope my trip back from cmb Doh will operate a QR flight instead of any other under one alliance .

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers.

good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

For the price we paid, I couldn’t complain. Was good value for money. Service was excellent but food was mediocre. Crew were excellent and spoke English. You will never go hungry. The food was ample but was mediocre. Entertainment limited and wifi doesn’t all allow you to access some social media. The best part was comfortable seats and bed (business class) with a screen to close out the rest of the cabin.

For the price we paid, we had a really good flight. The seats and bed (business class) was extremely comfortable. I have no complaints. The crew were very attentive and helpful. They spoke English and there were no misunderstanding although their English wasn’t perfect or fluent. You will never go hungry as there was ample food and drinks but their food for mediocre. The entertainment was limited to older movies and the wifi didn’t allow you to access some Social media. Apart from the above, it was a very pleasant flight. Would highly recommend them.

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

A lot of value considering the cheap ticket prices. All meals served were Chinese food. Would fly them again considering the ticket was half the price of any others
