I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

I needed internet for critical matters and it never worked.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

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.

The flight was cancelled, so why are you asking me how the flight was?

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

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.
