A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

My flight was late from US to Frankfurt so I missed my connecting flight flight and I had to wait for long to catch the next flight which was very tiring. Otherwise everyone was very nice.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Crew was not happy. Very uncomfortable seats. When person leans back in front of you the screen is too close to me. Food was awful.

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update

Everything went really well. Snacks could be better and there was no tea/coffee service after dinner. Crew was helpful and friendly.
