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.

Empty seats next to me - wish it had been for a longer flight!!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

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!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

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.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

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.

At the transit could be less time not like 12 hour 6 hours the mix should be 4 hour, thanks

787-9 TOO OLD AIRCRAFT , MY SEAT BELT INCORRECTLY FIXED, THE TRAY TABLE SLIDING, REPORTED BOTH , NO CURTESY BY CABIN MANAGER TO APOLOGIZE AT LEAST . FOOD WAS OVERCOOKED : THE PRESENCE OF A CHEF IS JUST A PROMOTIONAL PLOY , WINES EXCELLENT . THE FARE COST IS EQUIVALENT TO QUATAR , BUT TK IS FAR FROM MATCHING THEIR LEVEL BOTH BY AIRCRAFT , FOOD AND SERVICE .. I WOULD NOT TRAVEL BUSINESS WITH TK ANY LONGER .

I would appreciate having pillows, blankets, towels, and amenity kits readily available at every passenger’s seat, so that all passengers can easily use them whenever needed during the flight.

We were charged for checking in our bags! One bag per person was supposed to have been included in the ticket price, and yet Turkish Airlines charged us nearly $200 per bag!

Amazing service on board in business class. The lounges are also great. The inflight entertainment could do with a larger selection and the food choices more but overall, very pleased.

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.

Very bad overall. The comfort level was undeniably uncomfortable. The in-flight entertainment was no good because my screen froze and “wasn’t able to reset”. The staff were rude and non-helpful. Instead of offering me an upgrade for all inconveniences for the ticket, and seat I paid extra for, I was offered a downgraded seat all the way at the back of the aircraft. The flight was delayed for so long, making the experience at the layover airport that much more unpleasant.

Not a good experience from Lagos was very terrible paying for one extra bag is #403,600 in dollars is $331 which is too high and when get to Ny I don’t receive my bag till 2nd day some of my stuff was damaged am not really happy with Turkish Airlines very poor services.

The flight was very dirty and the food was very bad

I found it okay. Did not think the food was that great. And the service could have been better. Seat was a little cramped. Delay getting to Istanbul made me rush all the way across the airport to get to the connection. This was a not good experience.

Business Class Service was unacceptable. 7 flight time changes and delays

One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

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 :/

Seats very small and unable to pre purchase internet or seat upgrades

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

Good staff, good intent, decent entertainment. More seat space would always be of benefit

They have misplaced my one checked bag which I have not received in Philadelphia and have lodged complaint with American Airlines, the staff of Indigo was rude with us, at the checking counter, I think she purposely withheld my one of the checked bag, because the American Airlines staff told me that bag was not received at Doha airport. Kindly help me with one of my checked bag to get it. My flight was from Mumbai to Doha and then Doha to Philadelphia.

Polite and helpful crew. My son developed fever. Crew members came and gave him medication and also came and enquired about his health several times.

The overall experience for the price we paid was mediocre. Nothing outstanding! Check in process was standard. Flight attendants could have been more well mannered. I found it rude when the attendant nudged me with the snack box to grab my attention when not looking. She could have said ,’excuse me’ instead. My son’s in flight entertainment was not working. The food was not great either. The snack options were not so great with kids in mind. Overall, might not travel qatar again.

I didn’t expect American Airlines. I excepted QTAR AIR LINES. From KAYAK we are booking so in the kayak site it showed qathar air lines but operating American Airlines. I don’t like .

Restrooms weren’t working properly. Food choices were too exotic.

The cabin crew were kind, helpful, and polite. However, my flight from Abu Dhabi to Frankfurt was delayed, causing me to miss my connecting flight. As a result, my journey was significantly extended, leading to a much longer travel time than originally scheduled.

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

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

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

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

Etihad flight sector is a local . .give the same quality upto destination

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.

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

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

Loved the towel at the end. Service was frequent and perfect.

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.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

I remember flying with Lufthansa many years ago, and it used to be an amazing airline with more technologically savvy and roomy planes, but unfortunately that isn’t the case anymore. The space between the seats is much smaller, which is ok for short flights, but definitely not for across the Atlantic flights. Not sure if I’ll opt for Lufthansa the next time, maybe just if necessary.

I am deeply disappointed with Lufthansa’s treatment of my elderly parents during their recent flight. They were supposed to receive assistance with wheelchair service, but the experience was nothing short of a nightmare. Upon arriving at the airport, my parents were left stranded and confused, with no staff available to guide them. Despite being promised help, they were ignored by the ground staff, who were not only indifferent but also incredibly rude. To make matters worse, some of the employees made racist comments, which is absolutely unacceptable especially for passengers with special needs. We will never fly Lufthansa again and urge others to reconsider if they need assistance. My parents were left to navigate a busy airport on their own, which is both dangerous and stressful for elderly passengers with limited mobility. This level of neglect is inexcusable, especially from an airline that claims to prioritize passenger safety and comfort.

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.

Flight was delayed and caused us to miss connection in IAD. Then bags didn’t arrive at bag claim until 1.25 hours after flight landed.

Had to push staff to get good flight due to cancellation and delays for staff shortage
