it was great the cabin crew were polite and detail oriented.

My girlfriend had a health emergency and couldn’t board the flight. I asked for a refund, but you only offered half of the purchase price as a refund. Very disappointing.

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

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Flight was great. Smooth flying, movies good. Open seats allowed for good stretching.

Come on. A two hour, 7am flight and a small bottle of water and a tiny chocolate bar was provided. No coffee, no nothing. Poor.

Not enough veg food for passengers. I actually did not get veg food and starved the entire flight duration.

The crew on my Frankfurt to Chicago flight were outstanding!! Friendly, helpful and worth taking the time to write an excellent review on their behalf. I would fly Lufthansa again just because of their warmth, kindness and humor!

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

The staff were so very cheerful and happy! It really made my day to encounter such chipper folks throughout my journey
