We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

It was nice to be on a legacy airline, people try at least.

Mostly fine. Minor delays departing and arriving. Quite a cramped plane, not so much as regards legroom but very narrow seats. Quiet nice food. Non-working USB charger. Flight attendants were helpful but not particularly proactive — one had to work to get their attention (but all was fine once they notice you), very Dutch style:)

I travel frequently. The flight was late again... KLM should really try and be on time

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

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

Checked in is easy and it was a smooth flight from LAX to Munich

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

The Lufthansa part was wonderful. The short connection flight was not.

Nothing can I say I liked. Food was horrible. Entertainment system didn't work. Crew's attitude was bad. They all were Chinese and wanted to speak Chinese. Baggage missed my connection at Frankfurt even though it was more than 60 minutes for my connection. It came in the next flight of 3 hours later at 16.15 Portugal time but they said they will deliver to me next day. I requested them that I had to go to a dinner meeting so needed clothes and there were medical documents in the bag which I needed for my Doctors appointment on the next day morning. But all no use. Then I had to take taxi, go to airport at 9PM and collect my bags myself and brought bags to my hotel. Will avoid Lufthansa at any cost and same I will suggest to everybodyelse.

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again

The flight and crew was above average. However, there was a two hour delay.

Not good, the plane was warm , they were selling everything even water

The flight crew was outstanding. Small children running around and constantly crying was extremely annoying.

The boarding was a mess; I'm unclear why they can't organize it by boarding number.
