Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

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.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

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

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.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

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.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

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!

It was little disheartening and disappointing. Although flight staff did a good job. But customer service didn’t do anything to resolve my issue.

Very efficient and professional staff. Food was good and so was entertainment selection.

The service was good but the food was a NO

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

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 wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

Wish the flight attendants were more attentive in serving food

More leg space than other flights, but *maybe* narrower seats

Very delayed and uncomfortable seats. Nothing written in Urdu for Pakistanis. Tons of Pakistanis use the airline they should ensure the airline is accommodating them properly.

I was charged $604 for a bag that weighed 17 kg. I was given three different prices until they landed on the most expensive one and didn't budge a penny. It's ironic and a bit enraging because the total cost of my ticket was $468. I've traveled the world and never experienced these kind of prices for only one piece of checked luggage.

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.

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

Overall, the service was excellent, the crew verry professional, and departures and arrivals were perfect.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

Food was terrible. They ran out of options and gave me a bland undercooked pasta and veggies. Only middle seat was available to select although I paid extra. Baggage delayed at destination. Flight attendants not really helpful.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

I ended up in Lufthansa to Zagreb because of our delay

Great experience. Flight was on time and reached destination on time

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.

My flight was late from US to Frankfurt so I missed my connecting flight flight and I had to wait for long to catch the next flight which was very tiring. Otherwise everyone was very nice.
