Thanks for fixing the title of this question... the flight was a DELTA one marketed as a Korean Air flight. Which automatically makes it worse. The crew were actually rude in several cases and clearly lacked cultural sensitivity to the majority of the passengers (Koreans). This flight was also a minor heart attack before it started. Firstly, I thought I was buying a flight from Kayak, but it turns out they just acted as a front for this other company, UnderPricer, which took almost 24 hours to send a proper confirmation of the flight. We could not select the seats at checkout time either. We later submitted our seat selection to Korean Air, who proceeded to mess up the instructions to Delta, so our family was separated on the flight and our aisle seat was replaced with another middle seat.

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

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.

Excellent service, love the extra amenities (water bottles, blankets, etc.).

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

They had the same movie choice as my previous flight, not much of a choice, movies were not up to date, music was uninteresting. Other than sitting on the ground for 40 minutes after boarding the plane, with pilot telling us that they couldn't load the plane because of rain, (bullshit) We finally got into Bangkok of course 40 minutes late.

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.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

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.

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.

I will never ever book air india in the future. I was with my family and at delhi airport I had to go through too with horrible experience. My 12 years daughter saud that she will never come bqck to india the way people treated us. There was no line for bags drop off since we checked online and print tag at their Kiosk as per email instruction. People working at the counter were so careless and rude. They were keep talking to each other than taking care the customers. I will not recommend anyone to fly via air india. I had horrible experience. Especially, the staff at checking counters was very very rude and careless. I have feeling if air india won't change the way they doing their operations they will out of business in a few years. Air hostes were not happy . I did not see a smile on anyone in the plane. I called twice for the assistance and no one showed up. I hope you will sene this to the Hire authority. I left a video with an another employee of air india who asked me about my experiences. I hope they will make some changes ASAP. Regars, Mohinder Kumar

Food quality deteriorated after Tata aquired the airline. No alcoholic drinks till last meal on a long haul 15 hour flight. Entertaiment systems needs a complete overhaul.

only 3 meals in a 17 hr long flight. first meal after take off then nothing for 8hrs for people boarding at 2pm at orgin. you expect people to go without any food for 8 waking hours? there should have been 4 meals during a 17hr long flight. food quantity was also less. when asked for food the flight attended said they are about to begin food service then didnt do it for 2hours after saying that. terrible experience

Direct Connection is the biggest advantages. Aircrafts are now better but food and beverages could be better and served more often in a ultra long flight

Flies in the flight, broken seats, broken entertainment system and display - worst flight ever

We trusted KAYAK and Air India but no one is responds for the lost of baggage 🧳 2 (bags). My in laws are totally lost hope for this kind of situation to travel any more.

Very poor experience for the price paid. Airplane interior including seats were old and jaded. Seat tray table did not work properly. Head phone was defective and didn’t work. Food was mediocre
