At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Klm start boarding while somw air issue in the plan

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

Crew was excellent. Business class was poor on the short flight and mediocre at best on the international flight.

Very poor. Seats like economy class, food unbeatable, no charging, no entertainment, no WiFi, boarding by bus - no justification for calling and pricing this as business class

Boarding was delayed for an unknown reason for more than an hour. While the airplane was at the gate, the boarding time was moved by 10-20 minutes every 15 minutes. No entertainment on the plane.

During the flight, the fleas biting me in the plane.

Delay rushed to the next plane and bags didn’t arrive in chicago

Boarding could've been improved a bit, the rest is excellent.

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

Checking in took very long for whatever reason. Flight comfort these days is always poor so… Crew was great thought!

The seats are small and the movie selection was disappointing. However, the food was excellent and the cabin crew was attentive and kind.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

The flight attendants were rude. Seemed like they didn’t want to be there. Except for one girl that was really nice. Seats are sooooo uncomfortable. They give you a piece of paper and a thin cushion for a pillow and blanket that does nothing. Airlines have gone way downhill, especially United international flights. Food was disguting. Definitely flying ANA next time.

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!

It would have been better if the crew has supported my husband's reasons for needing to keep the space clear around his feet, rather than insisting that he put his knapsack in that space.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

Trip was smooth, good drew, average meal, almost cold coffee. Excellent landing. Did not enjoy going down the stairs, walking to the gate, walking up the stairs, going a long walk to the exchange gate, and going down the stairs again to be bussed all the way where we originally landed to take our next flight! Over all an average experience. Thank you.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious
