It was great. I had an exit row seat so I had a ton of legroom. The service was good and the food was decent.

It was great. I had an exit row seat so I had a ton of legroom. The service was good and the food was decent.

Aircraft used was a 10 year old 767 which is being maintained in excellent condition. Business class was very comfortable and reclined sufficiently to allow me to sleep. The crew were excellent and very attentive. The only two unfortunates were a) food quality, the beef was very tough and below the standard for business class service; and b) the onboard entertainment offered little for non-Mongolians. All around, I would gladly fly MIAT again.

The flight was on time and the aircraft new and well-maintained. Service was friendly and well carried out. Seating on the 737 MAX in business class was comfortable enough that I could doze off during the 4 hour flight. Arrival in Ulsan Baatar was on time and baggage delivered to the belt quickly. I was pleasantly surprised by the entire event and have no trouble recommending MIAT.

No entertainment display working whole flight it was like a veggie 😒

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Staff always with a smile and very helpful with my mom who has mobility issues.

It was amazing. I was not expecting the phenomenal customer service Asiana provides.

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

We took business class, It was comfortable and I was able to sleep.

Everything was perfect. A flight attendant even brought me snacks after I declined food due to my desire to force myself to follow the destination time zone.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

The boarding process was good. The toilet could be better maintained.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

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

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

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.

Took a long time for boarding. The flight was comfortable.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

Should have had business class line in immigration. Food quality suboptimal

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

Both my luggages were never sent from Istanbul. After 10 hour flight from DC to Turkey and another 12 hour layover in Istanbul Airport, I would’ve at least expected to find my luggages when I arrived in Addis Ababa, but that wasn’t the case. After 2 hours of waiting at the luggage carousel, we were told that our luggages would be arriving the next day after midnight. I was already so exhausted, that I hated having to come back to the airport the next day. Thankfully, I received both my luggages the following day. It’s just, the whole experience was exhausting.

The check in process at Istanbul airport caused my family a great deal of stress and disappointment due to the following factors: 1) WE HAD TO PAY US$330 for check on bags, despite holding Economy tickets that Turkish airlines website clearly states that flights from Istanbul to Miami had a 2 checked bags allowance. 2) Airport staff not only lacked empathy for senior travelers (75 yrs old and 71 yrs old), but were also rude as well. The supervisor at check it offered "if you don't pay for the bags, you can just remain and sleep at the airport for however long you wish. What a terrible way to treat customers !!! 3) We were bumped from agent to agent to agent FIVE times, showing everyone the communication we received telling us we had the 2 bags entitlement. Two elderly people lugging 4 suitcase around and around the Turkish terminal. Again, what a sad way to treat customers !!! 4) We need a case opened to get a refund for the amount we paid. Something is amiss, screams unethical, and sounds unscrupulous......At First , we were told we must pay for 4 bags. All of a sudden, it became 2 bags, and finally all 4 bags were checked on with payments demanded for 2. Why did it vary from agent to agent???? 5) OVERALL, A TERRIBLE AND SUSPICIOUSLLY UNSCRUPULOUS EXPERIENCE FLYING WITH TURKISH AIRLINES. WE ARE TERRIBLY DISAPPOINTED AND SAD THAT OUR VISIT TO A BEAUTIFUL CITY ENDED IN SUCH A HORRIBLE EXPERIENCE

5 unnecessary control before get in the craft. It is exagerated and very inefficient

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

One of the best flights I have been on in a while.

Here's a sample answer: "Honestly, I was really impressed with Turkish Airlines, but if I had to suggest one area for improvement, it would be: - *More efficient boarding process*: I noticed that boarding took a bit longer than expected, which might be frustrating for passengers with tight connections.

Not worth pay business class and get service economy class

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

In sharp contrast to the modern glitzy airport, boarding facilities were primitive. Passengers had to board buses and walk up steep stairs in bitter cold with carry-on baggages. I found no reason why aerobridge was not provided.
