It was a comfortable flight and the flight crew were lovely!

It was a comfortable flight and the flight crew were lovely!

I’ve always been impressed by the cleanliness of the toilets or, at least, its frequent monitoring, cleaning, and toiletry replacements. The in-flight service by flight attendants is superb.

I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.

The flight attendants seemed to be a little more grumpy this time. A350s could use more toilet stalls.

It was horrible. The flight crew was unfriendly and the food was absolutely horrible.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

The crew and my luggage was still pretty good after a long flight. They take good care of the luggage.

Food tasted pretty good. Boarding was very smooth and efficient, compared to all other airlines I’ve been on. I have flown EVA, Cathay, Asiana, British Airways, and many USA brands. Cabin attendants were also efficient and professional.

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 ac did not work and the plane was deployed for the AC BUT IT NEVER WORKED. I have high blood pressure and I was SWEATING AND NEARLY PASSED OUT. Do better.

For me it was a good experience… thank you Turkish Airlines

Old aircraft, very very low business class standards, no privacy between the seats, horrible old TVs, tiny bathrooms.

Good service, the airline also provided a traveling kit bag (tooth brush, socks, slippers, visor for sleeping).

The seats have to be one of the worst when it comes to comfort and you have to scramble around to out your handbag in the overhead. The food is still awful. Definitely will not travel on Turkish again and wouldn’t recommend it to anyone for sure.

It was very good and it was not my first time I always take Turkish air line for my travels

Food excellent Bathrooms improve cleanliness needed Staff fairly well attentive Entertainment fair Seats lie flat worked well

My flight was cancelled with no warning! I had to find out right at the airport when I arrived from my previous flight!

Excellent service. Made United 's business class look like a cattle car

I have been flying Turkish Airlines for the last 5 years it’s always great service, on time , excellent food, only one thing wasn’t reliable is their on board WiFi most of the time it doesn’t work.
