As always, it’s a pleasure to travel with KLM. It is one of my favorite airlines.

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

Amazing crew, delicious food and drink selection. 12hr felt more like a 4hrs. Comfortable beds. Can’t wait for the new business class cabin

Flying business class saves you. Once you get out of the terminal and onto the plane, it’s fine. The traffic at the gate is a horror. No organization at all. The fact that Business class is promised early boarding is a myth.

The seat was paid for but given for some different person .

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

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

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

Flight was delayed by a hour could have been better addressed. Flight was fine with great service by the flight attendants

All good. Didn’t get the seats I booked online. Luckily, copassanger cooperated! Mistake- I failed to verify connecting flight seats details at Mumbai. Staff at Mumbai airport to be blamed equally!

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

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

The flight was delayed an hour and a half while you tried to fix the plane so I missed my connecting flight in Chicago. In Chicago, it took an hour to get the luggage. Then the conveyor belt was broken where I have to transfer my flight from an international flight to the continuing flight so I had to carry a large suitcase through the airport. The elevators were broken in the airport. I paid people to carry the luggage for me up the escalators in two different areas. The person who helped me get the new flight was outstanding. The temperature in the airport in Chicago was horrible. We were all sweating. It was the day from hell. That was after two hours in a security line in Athens. I have TSA pre-checked and global entry and I still waited. Two hours in a security line. Something has got to be done to stream line this service. After I’ve been through all of that in Athens, why do I have to go through it again in Chicago. It was the worst travel experience I have had in a long time. Your bathrooms have gotten so small that you can hardly get your butt on the toilet. You’ve taken the airspace out of the inside of the top of the toilet. It really makes for a miserable experience. Also on a 4 1/2 hour flight from Chicago to Los Angeles. The only thing we’re given is a bag of pretzels. REALLY!!

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

Boarded early, left early, arrived 40 mins early! A win win for me!

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

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