The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

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.

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.

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 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

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Delay, luggage didn’t arrive. Had to go the next day to collect it

Amazing! One of the best kept secrets in air travel!

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

IAH to Istanbul was outstanding across the board. The flight from Istanbul to Male was good, not great.

Good food and wine. Some of the Guy who are in charge to board Passengers on the plane couldn’t use the word “Please” to direct them drop their hand luggage to be loaded on Plane bcos he said the inside storage may not have enough room for all.

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???

Temperature in plane in both segments was warm. Otherwise, great experience

Love that they had a bassinet for our child during the flight. Thank you for that big time.

On my flight the menus showed different food and different was available. I think that was a miscommunication maybe. Other than that flight was wonderful.

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

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

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

We had a delay, but thankfully I made it to my connection. Overall it went smooth

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

Flight was delayed and missed my connection Lufthansa didn’t respond.

Was a good flight , well served by the flight attendants. Boarding went smoothly, flight was smooth.

Nothing went smooth. From being threatened to pay $400 for omitting my middle name by agents in India or somewhere. In addition, I couldn't get an answer on how much a third bag would cost despite numerous calls to Lufthansa. Then I couldn't check in online because they wanted evidence of residency. I told them I have dual citizenship but that didn't help. Last but not least, my luggage didn't make it to my destination. I had Christmas presents that didn't get to family members on time. I also had to wait the entire day to have it delivered. I have never had such a bad experience with an airline. This is how you loose customers

It started well but flight was cancelled and they created a nightmare rebooking. It is two days later and we still haven’t reached our destination. I am in Amsterdam waiting on transfer desk to open (later than other airlines) to hopefully get a boarding pass. Once that problem is solved we will just pray this flight isn’t cancelled too.

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

The United Airlines crew that operated this flight was subpar. They didn’t

Flight crew was among the best I’ve ever seen

Boing 747-8’s are showing their age. The seat back screens are somewhat unresponsive. Even putting the seat “in its original and upright position” required assistance from the guy behind me-after I helped the lady in front of me! I left a ball cap on board. I’ll be flying back in four weeks. I wonder if Lufthansa has a list a found for that kind of stuff in Frankfurt?

I liked that the chairs don't go back too far. I did not like the entertainment system, which was really terrible by industry standards. The crew were unpleasant. The main meal was terrible, the morning meal was quite good.

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

Lufthansa flights were great. United flight from houston to Frankfurt had very small seats with almost no space

I dropped my wallet under my seat on this flight with all of my money and credit card. I requested to be able to go back and retrieve it but Lufthansa denied my request. I went to the Customer Services and they called Lost and Found but I was told nothing found would be turned in until around 12:00pm. My next flight was leaving so I was unable to check to see if my wallet was turned in. I will never fly with Lufthansa again.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

Horrible experience. They lost my luggage and still can’t find it. The plane ride was below average. Food also terrible compared to other airlines.

The team/crew were excellent. The USB ports were not working/broken, I tried multiple ports and also asked a staff member to check other ports on the flight, she confirmed they were not working!

It was good but my seat was terrible for a long trip, too small

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.

The flight itself was great… the only problem for me was the flight delayed both departure & connection.. instead of the 26 hrs (long enough) was an additional 4 hours more that took an aim to my body..other than that I’m pleased.
