Pros: "One flight attendant in particular was outstanding, Eva. Because of her, I would definitely consider Lufthansa for our next trip to Europe!! She mot definitely went above and beyond in her service and professionalism."
Pros: "Best part was how Lufthansa took care of travellers whose connection time was short. They had ground crew waiting and who escorted us through customs, and then drove us to the gate. This is how passengers should be treated. ~ Excellent movie selection ~ Great flight attendants"

I felt that I could get easily lost between flights and not have time to get to the Frankfurt/Denver flight. I told this to the person at the gate in Zurich, and he immediately arranged for someone to meet me in Frankfurt and take me there. I was met by Maika in Frankfurt and she was just excellent--personable and efficient and really helpful. I'm sorry I couldn't remember the name of the person at the gate in Zurich. He was also great. I wouldn't have done this if I had had more time, but this really made my day (and my flight!) ! Thank you!"

THEY TOOK OUT ALL OF MY HOUSE, AND CAR KEYS , AND MY REMOTE CONTROL FOR MY PICKUP, (ALL ON ONE RING), AND DID N O T PUT THEM BACK INTO MY BAG. I WILL N E V E R FLY AUSTRIA AIRLINES, OR LUFTHANSA AGAIN! I SENT AN EMAIL TO YOUR CUSTOMER RELATIONS DEPT...customer.services@lufthansa 3 times and they failed delivery."
Pros: "Nonstop flight."
Cons: "The seats are the most uncomfortable I've ever sat in. The food from Frankfurt to Denver was subpar. The first 2 hours were very bumpy and unusual for that part of an Europe to USA crossing. The spacing of the middle seats with the support struts having to straddle for 13 hours is too much. I could go on, but you really need to rethink the design and customer service on your long haul flights."
Pros: "Hope to make today's flight home! Time will tell."
Pros: "The staff was so prompt and friendly, the food was the best airplane food I've ever had, and the entertainment options were great!"

Excellent service in Economy Class!!"
Cons: "At times I felt too cold, despite the blanket."
Pros: "Inflight entertainment was excellent, the food and service was excellent, no complaints except for legroom."

Pros: "You'r aamazing, great deals! Thank you!"
Pros: "Considering this was a 10 hour flight, I thought the plane was comfortable with decent leg room in economy class. We were served two hot meals, both of which were very good. There was also complimentary wine, beer, and spirits on board. It's been a while since I've flown overseas and was impressed with the wide array of available movies and in-flight entertainment. The crew was great and very attentive."
Cons: "It was the most chaotic boarding process I have ever seen. They had us at a gate with seats for about 50 people so people were crowded into the walkway area of the terminal. The announcements were very hard to hear if you weren't right by the person making them. There was no orderly boarding. Instead, there was a mad rush for those that weren't elite status of some sort to begin boarding."
Cons: "Food was not that good"
Pros: "Great crew, very attentive. Excellent food and beverages! You don't get off of Lufthansa flight hungry! Good choice of entertainment. Lufthansa really knows how to take care of its customers on long-haul flights!"

Pros: "Lufthansa was very professional, in terms of their crews, procedures, and condition of the aircraft."
Cons: "I bought an aisle seat in the center section near the back of the plane because the diagram of the plane's seating area showed an empty space in front of the row I picked. On the actual plane, it was simply a normal row, with no extra space in front of it. Going to register complaint with Lufthansa and seek refund of seat cost."
