It was my first KLM flight and I loved it. Thank you very much.

It was my first KLM flight and I loved it. Thank you very much.

It will get you where you want to go. Power did not work on ether of the 2 planes but staff was lovely. Wood like to see a improvement to the food as the amount was small but the main issue is the food isn't tyed to the location your going to the airlines own culture. So that would have been nice. Staff was crazy nice and even helped me with a very tight connection

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

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

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

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

The whole trip was excellent. The only thing I would change is the temperature of the plane was a bit high which made it uncomfortable to sleep.

KLM is my favourite airline. Never ever let us down.Staff are first class.

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

On time, great food, good drink selection! Only down was alcohol-free lounge. Lufthansa had a much better offering!

The seat 7A had no padding. I needed to sit on the provided pillow.

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

The trip had a 19 hour layover, and no hotel accommodation was provided. This a shame for an airline to do to their customers. I will not only stop flying with Turkish Airlines, I will make sure anyone I know avoid Turkish Airlines because of how lousy their layover system is.

Four of my family members was settled in a different seats. I paid extra $200 dollars for 4 seats just to be all together, but they settled us on separated seats. After a lots of time they put us 2 and 2. My kids are 9 and 13 . How i can leave them alone???

Horrible customer service , employees are rude , angry and can’t speak any language other than Turkish well,

Great service, great food, and comfortable business class seats... Friendly and professional flight attendants and ground crew, overall 5 star experience!

My whole body was paining after such long flight. Seats are small. Leg space is too small. Food is good.

The seat in the 787 was broken and did not keep us in the upright position. Also the entertainment system was broken for some channels and only had audio and no visual display.

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

The service was good but the food was a NO

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Overall it was a very good experience. Boarding was efficient and well organized. The cabin crew were excellent. The meals were tasty and quite filling. The warm bread rolls were a nice touch. Seats were comfortable even if they were a little narrow. Entertainment selection was excellent.

I like is everything is good seets are little uncomfortable during the long flight ✈️ Doha to us , luggage 🧳 came too late overall very nice thank you for all

Bag check in at DC was slow. Boarding process was slow more due to customers unfamiliar with how to board properly. Food and service was excellent!

Found out we were limited to one carry on item per person as we checked in and weight. This requirement has never happened to us before. Then we get on the plane and it's apparent why. There is barely any space on this plane. I sat in the middle row middle seat and shared a single section of leg room with the stranger next to me. Had to put my backpack in the overhead which barely fit and made it so I didn't want to bother getting my things out of it later like my eye mask. There was an angry man complaining about his seat and demanding to be switched for a good 15 to 20 minutes as we were boarding. To the flight attendants' credit, they didn't give into him (not that they could have), but it definitely made for an unpleasant experience. Also there was a child running up and down the aisle during the flight including takeoff and landing. The crew told the parents but they just smiled and continued letting the kid do this. This was p annoying and not to mention dangerous for the kid

Except for the first row in business rest of the seat has less leg space while fully flat

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

Etihad charged me for 2 check in bags. On Kayak search results price was showing 2 check in bags were included. Kayak need to reimburse me for these additional charges and metal agony and distress. Thanks.

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Should have had business class line in immigration. Food quality suboptimal

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

It feels like the seat did not have any cushion and just ply wood. The seats are so compact that no one would sit comfortably. I am a slim person and it was super hard for me to move in the seat just imagine what someone else would feel. This airline would be my last option. Singapore Air and Emirates are far far far better than this. Do not travel even for free.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping

Had a delayed flight that caused me to miss all of my flights. Supposedly I was rebooked. When I got to my next connecting flight there was no ticket for me. I spent hours working with an agent. And they still couldn’t get it right. I will arrive home more that 24 hours later than my original schedule. Totally inept and frustrating experience.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

I had to fly United where the flight crew was atrocious

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

My flight was delayed by 10h the crew was useless didn’t care a bit once we landed they couldn’t get the luggage out of the airplane for another 2h old plain old crew poor service I’ll never fly Lufthansa again

Boarding was 20 minutes late. Had to ride shuttle bus to plane in order to board.

Just RETURN the LOST and FOUND items to the LUFTHANSA passengers, instead of just saying "sorry"

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.
