Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

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!

You should not have to pay for WiFi in business class

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

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

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. It was supposed to have wifi but that did not work.

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

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

Took a long time for boarding. The flight was comfortable.

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

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

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

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

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

It was a very full flight, makes it harder for flight crew.

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.

SEA to Munich flight was turbulent and you could hear rattling in the plane. The food was TERRIBLE, return flight was better. We will not fly Lufthansa in the future.

Flight took off late. Flew business class. Lunch choice was chicken or vegetarian gruel. Chicken was gone by the time the flight attendant got to me. Got the salad, rolls, and desert. Skipped the vegetarian gruel. Almost broke a tooth on the roll. Suspect at it was least three days old...bird food. Wheelchair service (for spouse) at ATH was outstanding. Wheelchair service at FRA was mediocre as usual/expected.

Everything went well with our flight. I would like to be able to see my connecting flight gate on the flight . We had a short connection time we were nervous and they changed the gate we arrived at. They told us where we were entering and it required a shuttle ride and a map of München airport would have been good on the flight .

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.

They lost my luggage for five days and did not keep me notified of the progress at all.
