Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress

First time flying with UA and it was a great experience. Thank you

Staff on board was excellent. Positive upbeat helpful- like it used to be.

United has come a long way, it’s been a fantastic experience traveling with them.

Older aircraft, no meal, only food was for purchase. Not impressed United.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

Everything was great, only problem was that flights were delayed

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Knowing that there was weather in other areas of the world, united airlines should have planned better than it did. The flight was 5 hours late. United has no regard for its customers

Flight itself fine, big problem with KAYAK. Revised e-ticket sent in July stated departure LHR 10:55, arrival SFO 13:45. (a believable local arrival time given flight length and time difference). When we got to LHR there was no 10:55 flight to SFO and were advised that in fact flight LH2473 was arriving in MUNICH at 13:45pm, and that we would need to get a connecting flight arriving in SFO at 18:55 local time - over 5 hours later than expected. 1) you the booking agent made an error on the revised e-ticket you sent, omitting the Munich stopover and incorrect SFO arrival time. 2) I booked a DIRECT flight and 3) we had to cancel plans this end as a result, even though the team at LHR did a great job moving us to a later direct flight getting us in 2 hours earlier than the flight from munich would have.
