Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

Crew was outstanding, helpful and friendly. Food is deteriorating. The snack at the end of the flight was not good, a greasy moosh of toast cheese snd other unidentifiable ingredients. Coming from Germany a pretzl with butter would have been better. Entertainment had a great selection.

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

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

Easy checkin. Things went off without a hitch. The the movie selection for the flight wasn’t great, though.

Never happened. Flight was delayed. Had to be re rojyed
