It was okay. Mothers with rowdy children should be invited to sit in front of them.

It was okay. Mothers with rowdy children should be invited to sit in front of them.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Boarding procedure should have the crew and personnel who are more trained, in a sense of precisely knowing what can be done and what cannot. They do not have the exact information on what you should do in the first place, also the boarding itself was slightly delayed due to the aircraft "not being ready".

..it was short.. I didn't like that my red bag went out completely stained with black stains..That's probably some airport staff bad handling but still

There was more leg room than on the overseas flight, which was nice. Boarding was very well organized and the flight very comfortable.

The flight was delayed more than 1.5 hours. Phone calls to united did not satisfy our need to get to Chicago to met family for fight to europe. I was told the flight was booked thru luftansa and united could not make adjustments. When call luftansa they were unaware of the significant delay on the united flight out of mci. They would not authorize a flight change. We went to the airport, as if we would be flying as scheduled, United checked us in, as if our flight would leave as scheduled. We took our bag to be checked to the baggage drop and the agent their confirmed our flight was significantly delayed. She worked for 30 min to get us on another flight. We ended up flying to Denver then to Munich. The rest of the family that flew to Chicago for our meet up and flight to Europe ended up flying to Munich alone. We meet up in Munich for our last leg to luxembourg. In luxembourg we learned on bag was scheduled on our delayed flight. The flight was canceled and we did not receive the bag in lux. We filed a lost back claim. Now 3 days later we STILL do not have the bag. It is apparently in luxembourg and they maybe tried to deliver, however the names on the door of the air b&b do not match the name on the baggage claim so the French speaking delivery person called no one could understand him so he took the bag and left. My brother, traveling with me under a different reservation , has been without essentials for 3 days. One or all of us has stayed "home" each day waiting on the bag. Today was my turn. Delivery window was 10:30 to 2:30. No attempt to knock or ring bell. After the hang up call, my brother called me and told me to check the door. There was nothing there. No sign of attempted delivery, no delivery man, nothing. Being unable to change clothes and having family members take turns waiting on a bag that never comes has ruined this family vacation. Thanks United/Luftansa

The flight left an hour late and no explanation. Food was basically a few snacks out of bags and tiny cup of soda. Crew was pretty friendly.

The The check in process was terrible on both ends. It was not clear if we should use the United, Lufthansa, or Aragrant number. It took over an hour to check in on the front end – and then at return the Lufthansa online check in failed multiple times and only after two calls to their phone number could we accomplish the task. The link to the Kayak site provided no access for check in. This difficulty and ambiguity on both ends will affect our interest in using Kayak for foreign travel in the future.

You lost my bag then waiting on the phone for 30 mins for customer service just to be directed to call another number

Boarding staff, crew and food needs a lot of improvement!! It was awful Aircraft was old with minimal legspace
