Staff was very professional friendly food was okay i used the lufthansa app and it was great told me immediately what gate I should go i would fly with lufthansa anytime

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

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

Everything was perfect. That is the most beautiful flight over thenDolomites.

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.

The flight to Frankfurt was delayed. Consequently the connecting flight to Seattle could not be boarded. Lufthansa accommodated in a Cattle Class Flight where the Seats and foods were horrible. I had only Hobson’s Choice and boarded the flight and reached Seattle 3hours later than my scheduled arrival.

No Wi-Fi or food unless you pay an expensive fee.

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa
