Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

Boarding was fast and efficient. The crew was super friendly. Since it’s a budget airline and it’s a short flight, I can’t expect food or entertainment.

If you buy a cabin luggage, but don’t need it for your kids, so you will end up with mixed priorities. And you will need to use non priority line

Boarding waiting outside in storm and rain is not OK

East check in and security. They are always delayed though. ALWAYS!

Amazed at huge number of people who hadn’t booked cabin bags with big troller cases and rucksacks, not being stopped, what’s the point in following rules or paying more if you don't have to bother?

It was a short flight (1.2h), and everything went smoothly.

Very good, everything went straight forward, boarding, during the flight, landing and all on time Well done

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Aircraft had fairly roomy seats on economy. Food was good (beef dinner).

Broken seat did not recline fully, broken footrest, no air vents, no electricity for charging devices, outlets for headphones or isb did not work. Rude crew. Horrible experience. Would never fly Lufthansa again

They did not serve my special meal request after departure of airplane

It was a very smooth and on time flight experience. The crew was really friendly and polite. We were well informed about the flight, etc.

Our Lufthansa flight MUC to IAD was cancelled 90 minutes after boarding requiring a night in Munich. Nightmare.

Flight was late incoming. Crew did a nice job trying to accelerate boarding. Flight was fine. My complaint is with the staff in the Lufthansa lounge in Paris. Clearly the desk attendant doesn’t like her job. Was rude and unhelpful. What’s the point?

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.

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.
