I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

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

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

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

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

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

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.

Service and food were decent, seats are a bit too narrow. Leg room is normal. Bathroom should be cleaned more frequently. WiFi is cumbersome and should be simplified.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

Same as before boarding process and lack of crew experience in the process

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

The flight was cancelled due to tech problem with the plane

The whole experience was very disappointing. Drinks could have been served and offered more frequently. The seats were reasonable but considering I paid for premium economy, I felt cheated. I flew premium economy with Japanese Airlines ANA 5 years ago and their service was by far, superior. We had access to the club lounge, better seats and excellent service. Out of 10, I would rate the experience as 4. Everything felt cheap and the Airbus aircraft are far better and more comfortable

Flight was okay however bags were left in London even though we had a 7 hour layover. Bags are yet to be confirmed to reach final destination. Horrible work.

Quiet and comfortable aircraft, pretty smooth flight. Very comfortable business class cabin with decent entertainment. Good service from the crew. All in all a good experience.

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Too much long line at the TSA and Security. Prepare for long walk for baggage claim.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

The boarding process was quite loud and chaotic. The flight attendants kept barking over the PA system about people needing to only stow large items in the overhead bins. During the one and only service, I was hit by the service cart. At the same time, a passenger was returning from the bathroom and the crew definitely saw him but stopped a few seats short of allowing him to sit down before starting service and made him wait a good 10 minutes before passing his seat and allowing him to sit down, after which he had to ask for his snack and beverage or he would have been passed over. Neither flight attendant thanked passengers as they left; in fact, I did not see them again once the plane door was opened.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.
