Same day canceled, we were never informed and had to pay more with worse seating on another airline.

Same day canceled, we were never informed and had to pay more with worse seating on another airline.

Flight itself excellent, but delayed so missed connection & got to destination 2 hrs later

Boarding was organized. Old plane. Seat fairly comfortable. Business Class much too large so you don’t receive as much attention as you should considering what you pay for the seat.

We were in business class. the angled seats in that class do not have a real window view & the placement of the controls are bad. But we knew that. But the food options were mediocre. The taste was fine, but the size was for a child. It’s just really feels like United is skimping on everything. Even when we were in the Polaris lounge they did not have diet sodas. They said they were out no Coke zero no Diet Coke, etc. I do not think the portion of nuts they serve on the plane could get any smaller. Really a minimal service and offer for what you’re paying for in business.

More water distribution throughout flight. Food quality poor and hot items delivered not hot on both attempts. Not United Standards

The Frankfurt airport is just not that easy to get around. Having to get from one end of the airport to the other when it was not well marked was a challenge. The flight itself was fine. I would fly with United again.

Air conditioning in the plane wasn’t working at boarding, this resulted in a delayed departure whilst they addressed the situation. The cabin was uncomfortably hot.

Flight was delayed for an hour and it caused a chain reaction to our connecting flight although we made it but we had to rush and run !!!! To top it off, all our luggages were DELAYED!!!!

The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink

This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.

Never made it to Lufthansa because of Air Canadas negligence.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

There is more space in this economy seat. It felt like a better layout, not so cramped.

The staff was not at pleasant as those on the first leg of our trip.

Crew was excellent. Sat us together after the airline changed our seats. This was the smaller plane/shorter flight so no entertainment or food.

Boarding was one hour late. Gate notification was incorrect (notification said gate 17, actual was gate 14). Took shuttle bus to board the plane. Late arrival of plane at Turin impacted travel arrangements to the event.

They canceled our flight right before it was to take off and then we stood in line for four hours to make other arrangements. It completely ruined our trip.

My baggage has been lost for the last 6 days! The problem originated at LAX with Lufthansa, which was a very big disappointment from LAX to Munich. The flight was delayed over an hour, the overhead bins on the window side are too small for most carryon's, the in-seat video screen were very poor as they would not respond to your touch quickly and would stop and start all over again, the earphone jacks are not like most standard ones, the seats still has wrappers and trash in pockets and on the seats. and there was no USB outlet to charge your phone or other devices. The German reputation for quality is bogus with this airline. BUT the responsibility for delivering my luggage became Air Dolomiti's as they were the last leg of the trip. The baggage area was chaos because several flights arrived at once. I took me over an hour to file a claim, the agent entered my info incorrectly, and the contact numbers for Lost and Found at the airport was never answered. I have never been called by Air Dolomiti or the baggage delivery company. I had to do all the calling. AD's live agents gave me two wrong phone numbers for the baggage company. When I finally got the right one on my third call, OF COURSE, no one answers and I still do not have any information on when my bags should arrive. VERY UNPROFESSIONAL operations by Lufthansa and Air Dolomiti. I will make sure I book any other air carriers on the rest of my flights to Italy this year.

Lufhtansa has and can do better. The food was inedible. No individual light for reading.
