Good legroom. Attentive crew. Wine quality poor, you can do better

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

Great experience. Flight was on time and reached destination on time

I meant this flight was not good, the one from Tirana to Frankfurt was better!

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

food, movie entertainment upgraded current, interconnecting flights being on time, we have a 24-hour overlay

Exit row seat that cost extra to book had a bad monitor marked as out of order, so clearly something they should have fixed.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

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

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.
