Seats were cramped, too little room, not particularly comfortable. Service was excellent.

This leg of the trip was ok, though the check in agent could have given us assigned seats. I have a feeling though that agent could not as it became clear later on. Please see below. However, the leg from Zurich to San Francisco was horrendous. We only had less than 1.5 hours to transfer to a different gate using transfer train. We asked at the business lounge and were told to see the gate agent. When we went there there was a long line. As we approached business class desk, we were yelled at and the agent said "I will not talk to you". After a long wait, we were then told our seats will be assigned at the boarding time!!! After a time, the agent announced for volunteers as the business class was overbooked. We did get seats in the end but were separated at which point, we just decided it was not worth trying to ask for seats. I am not sure I will ever use Arrant Grant. I understand the Arrant Grant need to charge commission. However, what Lufthansa charged $10315.80 Canadian dollars ($7316.17 US dollars) was so much less than $12670.80 Arrant Grant charged me. I think commission of $5354,53 US dollars is too excessive. Also, I tried to upgrade to First Class and was told that we had upgraded once already and couldn't upgrade again. So, a terrible experience.

I got a fortunate upgrade to First Class. The trip was outstanding in every regard, with a particular shout-out to the crew, who were outstanding.

Only the dishtray thing. The leg room was reasonable but the trays sitting too long and space small no space with food plastci cover and utensil wrappers. It got cluttered fast. Perhaps provide tiny trash bags?..

Boarding was very slow and unorganized. As a result we were delayed for 25 minutes crew is not friendly. food , entertainment and service was mediocre I bought in flight internet and paid $42.61 it did not eben worked after 10 minutes and no one helped I would like a refund on that please

Excellent excellent flight! I’m sure it helped that the turbulence and the weather cooperated, but the staff was wonderful. The legroom was perfect and my husband is 6‘1“ and he felt perfectly fine. Best flight I’ve taken in a long time.

The transfer was awful, everyone was running to catch the flight, there was no information on the process. We git to the gate and the boarding was late and had to stay in different lines but there was no guidance. The flight was late and uncomfortable, probably one of the worst flights I have been on. The luggage was sent to a different terminal and still did not make back to us.

The awful part was the customs delays at ZRH. The good part is the flight was delayed long enough to accommodate. The flight itself was fairly comfortable.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

Not good. We returned on united airlines and the food was horrible.

Seats needs to be wirer and food is very poor

Pretty much the exact same comments for this flight, there was crazy weather!

I have been flying united for a long time but now I’m done

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

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.

We love United Premium Plus! So comfortable without the cost of Polaris Club. The crew was so attentive and friendly!!

I have to wait for plane in Denver for three hours. I don’t receive my luggage in Denver. I come back home without the luggage and I wait till next day to see my luggage again. Not really good experience with United airlines. I’m sorry to say that.

Excellent as always. Had issues checking-in online. Please fix.

Everything about the flight was good. My one complaint would be that we were required to pay for a seat in order to select our seats before the flight. When I pay for a ticket I think the seat selection should be included.

Crew was wonderful and attentive. Chris (I think that was his name as I was seated in the back in 52F) was amazing and funny. The captain was informative and did everything to get us to Denver as close to on time as possible. Bags came quickly at baggage claim. Online check in would not allow me to change my seat 24 hours ahead of time with dozens of seats showing open and I really do not enjoy being in the back of the plane for long international flights.

Cheapflights did not forward the payment for seat assignments, and my partner and I were separated and given center (B and E) seats. Will be requesting a refund.

Way too crampled. Charge more and put in less seats.

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

I liked the flight, the attendants, and the comfort. But the gate for boarding was poor. Even the elderly had to climb down many many steps to the bus and climb up to the plane.

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

The food that was served was superb!!! Awesome snacks!!! Frequent drink service!!! To me, this was shocking. I took a British Airways flight from Denver to London for the first leg of my trip and the food was horrendous. Thank you for keeping us fed and satiated on such a long flight!!!!

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.

This flight went smoothly and the economy plus free upgrade worked very well.

Boarding process was late Could do a pre-announcement of flight status.

British airways needs to improve their luggage handling process and communications. The luggage was lost/left in UK. But, this was not communicated to me as a traveler and because of the wait at the carousel in Seattle (we have to go through customs and immigration on arrival to US) I missed the connecting flight and had to be rebooked. No one informed me that the luggage wasn't there, and there was no one there at the carousel to check with or help me get through security faster. I wasn't the only one- there were a lot of people waiting for luggage that didn't arrive.

The travel on premium economy class was very positive. Comfortable with plenty of space and leg room. The service throughout was top notch. Crew members were kind and helpful. Food and entertainment were excellent.

Long line with check in at the DIA British Airway counter.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

We never made it onto this flight due to BA's lackluster organisation.

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.

My problem was with the onward connection between London Heathrow and Washington IAD. The flight was several times changed.
