Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

We were moved twice on flights to the point we weren’t even on Lufthansa anymore. We had to fly united. Lost paid extra leg room twice. To top it all off we’re forced to pay $375 and $275, respectively for you luggage that was considered sports luggage. We were told it would be Lufthansa fares l, from the united desk, AND WE DIDN'T EVEN HAVE A LUFTHANSA FLIGHT! I’ll be calling once my trip is over on October 7th to all airlines and Kayak. This was ridiculous!

Everything went smoothly and the staff was very kind. I’m glad I purchased the extra leg room for my long flight; it was totally worth it. We were served 2 meals for a 9 hour flight which I was not expecting and they were very tasty. I appreciated them being vegetarian. Customs line in Munich was long; I had a choice to have a 1 hr 40 min layover or 2 hr 40 min layover; I took the longer layover which I was thankful for because my flight was delayed 30 minutes and there’s a good chance I would have missed my connecting flight. This was my very first international flight and I would fly Discover again without hesitation. Thank you for taking good care of me!

I liked everything BUT the temperature. It was freezing and now I am sick.

Pretty normal flight was delayed due to traffic could have missed connecting flight to Venice but crew kept us well informed so we made it

Flight was on time and pretty standard. No Hiccups. I have no complaints, which is a lot to say about a 12 hour flight.

-The seats could be roomier -The entertainment in English could be more current! The moves were very old!!! -They served too many carbs! What happened to fruit and yogurt!!!!

We upgraded to premium economy and it made a difference in a 12 hr flight. I didn’t like that we had to deplane in the tarmac with our carryon luggage. Other than that, it was ok.

Everything was much better than I had expected, since I hadn’t heard of your airline before. I hope to take advantage of your excellent service again.

Staff were nice, we left on time and arrived early, food was good. Unfortunately, they lost one of our bags and have been unable to find it. So we are in Italy for a week for my husband‘s birthday and he does not have any of his clothing.

They gave us sandwiches as a meal twice. Snacks mid flight with cookies and a tuna panini. Then just the same tuna panini for dinner. That was it.

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

The staff was very good, the only thing was the air conditioning wasn't working during the boarding process so it was very hot inside the plane until we got airborne. The food wasn't great, the chicken was dry and hard to cut, the ravioli was ok and the little pizza pocket thing was pretty bad. Other than that is was a good flight all around

Better consideration for families traveling with a disabled person. They insisted each person hold their own boarding pass on their own devices and gave us a hard time accepting eight boarding passes on a single device.
