I have no Comment. Super clean, Fantastic Crew, Food was delicious. Also wanted to add the Zurich Airport. Super nice people everything is in order super clean.

I like it very much it was a good experience with an excellent service

The crew and service was excellent. The food and entertainment were very good but not excellent.

Best service we’ve ever experienced! Special thanks to the crew member who took care of us throughout the journey. It was truly a once-in-a-lifetime experience. We love Swiss Air!

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

Boarding was very chaotic, we had to stand in two different lines that were not clearly marked, and the announcements were not understandable from the microphones, and we speak both German and English. We paid Kayak $120+ for seat assignments when we purchased our tickets but when we printed our boarding passes, suddenly we had been changed to 16 rows further back than our assigned seats we paid for. The seats we were assigned to on our boarding passes had no usable overhead bins and so we had to sit with our carry on backpacks underneath our feet in an already crowded space. One video/entertainment screen kept crashing and thus was useless for viewing anything. It was not an enjoyable flight.

The seat and leg room is small on the 2 seated row. Otherwise, very good crew and service.

Entertainment sounds were not good. Otherwise everything else was good.

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.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

The staff was incredible, very attentive, polite, made you feel like the center of the universe. They even all wrote me a happy birthday card. Truly just an amazing crew, cannot stress it enough.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

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.

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.

The hot towels before the second meal was an unexpected surprise. The crew was attentive and personable, and that’s a lot on a nine hour flight. And the hot pretzels were a kind of “auf wiedersehn “ to Germany.

Upgraded to business class and it was worth every dollar! The connection in Denver was way too tight time wise and going through customs there plus re-visiting security screen again caused me to miss my connecting flight. KAYAK should not allow that tight of connection on international flights.

During the flight there was a medical emergency. We were diverted. Of course I'm thankful they cared for the health of that passenger, but they did a poor job of communicating with the rest of us passengers. In the end we arrived at our destination several hours late, with no direction of how to rebook missed connecting flights. It all worked out in the end. Those of us that needed accommodations were put up in a hotel by Lufthansa until we could make it to our final destination. But it was United Airlines Personnel who really helped us navigate the process.

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

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.

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

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