The flight was excellent. Their was no service as we boarded, the flight attendants spent about 30 minutes just taking and not really caring that the cabin was about 80 degrees and did not offered any beverage to first class passengers or any passenger. The flight from DEN to ONT is not long but not under an hour, we received one drink and bag of chips if you were lucky. I was in first class…. I did leave my hat on the plane and it only took less than five minutes for a United rep to locate and bring it to me.

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Very Poor. Significant delays getting to Chicago and then very poor communication on delays in Chicago to Cleveland. We could have rented a car and driven there faster than the delays ended up being.

A little more friendliness from that crew of the day.

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

Ridiculous boarding. Enter the gate, walk down a staircase with bags, exit a building, get on a crowded bus, dropped off a few meters away from the aircraft, walk with bags to another set of stairs to board the aircraft. And all that during a pouring down rain, and with children. Ridiculous!!!

Lufthansa no longer offers any refreshments and snacks on short i.e., around 2 hrs flight. We still had full staff stewards/stewardesses. No idea why they were needed as there was no work for them during the flight

Flight was great. On time. Pleasant crew and responsible passengers. My only disappointment was that there was no coffee or tea offered. It was a short flight but a coffee would have been appreciated for what the price of tickets are now.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

The crew could deploy more customer focus and not frown when asked a question. I’m speaking of one lady in particular who raised a hand in my face for me to wait whe I tried to ask a question and never came back to me. Very unprofessional and rude.

They set someone on our assigned seats and we ended up finding seats for ourselves to ensure the family sits together.

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

We had to board and unboard, this could have been avoided

Always left late, food horrible and customer service not helpful.

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.
