This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

Very comfortable plane. The food was very good (for airplane food). The crew was great

It was okay. Mothers with rowdy children should be invited to sit in front of them.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

Well,I miss a flight to Stl with United,they send me to Stl with a different airline, but same day,which was great

NEVER TOOK THIS FLIGHT. LUFTHANSA CANCELED THIS FLIGHT WITHOUT ANY NOTICE. We were rerouted through Chicago on United airlines with a layover of five hours and then on American Airlines to St. Louis. The United club lounge in Chicago is good but there is no shower unlike Bangalore 080 lounge

At the gate I requested a change of seat to an aisle because of a medical issue, and I was graciously accommodated. Everyone was very pleasant and helpful.

Had to push staff to get good flight due to cancellation and delays for staff shortage

Tiny plane Had to gate check bags, a problem since we were flying back from an international vacation
