Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

Wifi is very frustrating - could not connect and therefore unable to work on the trip

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.

Our seats were not together - one on upstairs business class, the other nicer downstairs business class. Terrible!! A very nice agent worked hard with other passengers & got us upstairs together. Not ideal experience. Check in agent should have caught that! Asked about upgrade to first class for additional $2500 each. Refused upgrade saying we upgraded once already. We booked on business class to begin with so we’re NOT happy!!

Old planes and rude crew. They need a make over and better staff training. Even business class crew was rude and the hospitality was non existent.

They left a little late, contributing to our missed flight.

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.
