Nice, it was nice to have a free night's stay because our layover was over 18 hours.

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

Service and food were decent, seats are a bit too narrow. Leg room is normal. Bathroom should be cleaned more frequently. WiFi is cumbersome and should be simplified.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

Good service, the airline also provided a traveling kit bag (tooth brush, socks, slippers, visor for sleeping).

Food excellent Bathrooms improve cleanliness needed Staff fairly well attentive Entertainment fair Seats lie flat worked well

Connection was a headache due to a delay on arrival flight

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

I had connection flight. I barely made it to the next flight. I had to run to get to the next flight which was far away from where my first flight was landed . On top of that they search my stuff before boarding that added to the time. Food was ok but they forgot to serve our row with drink and also when it was our turn, they ran out of second option for food and we didn’t have any options for food.

Payed $140 xtra for seat arrangement Did not get the preselected seats neiter outbound nor inbound. Absolutely not worth the xtra money

not good missed my connection SAS did not leave me anywhere near enough time to make my connection. Ended up adding about 10 hours to my travel day

Overall a great experience. I didn’t like that they didn’t assign seats until we arrived at airport. All the employees we interacted with at the airport and on the flight were kind and helpful.

Since our earlier flight was delayed, we missed this flight and were rerouted on Lufthansa 2 days later.

Scandinavian Airlines is terrible. Flight was late. Lost luggage. Rude flight attendants. Terrible experience.

Ancient aircraft (busted armrests, poor cabin temperature with no option for passenger control). Garbage everywhere. Risible checking of safely conditions on landing. Also, late.

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

Maybe more diverse entertainment. Although the inflight cameras were amazing 10/10

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

I did bought anything… I don’t understand how this book appears to me . Ridiculous

The plane left over an hour late. I missed my connection going to Tokyo. They haven’t sent my bag to Thailand, where I ended up. It took me over 32 hours to get here. Very bad experience so far. I hope they can fix this and get my bag to me, within 24 hours it doesn’t look good at this time.

This flight did not take place because the passenger was in the hospital. We have made so many attempts to rebook this flight and have spoken to so many United Airlines representatives and everyone is giving you a different answer. It has become beyond frustrating to the point where we now have to seek legal help. This is a family of 4 so a lot of money was spent to purchase 4 tickets to go visit their daughter/sister who is a US servicewoman in Okinawa and to be treated with such disdain and disrespect is beyond reprehensible. The main traveler was given sent a letter by United confirming a refund on the tickets and to be able to use them but every attempt to use this has been met with a negative response so much so that the client is over stressed.

The pre-order only approach for fresh food is really challenging

the seat has a problem. the back had a hole.

The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

The seats on Lufthansa’s international business class on the A350-900 is the worst product in the market. Our chief purser was AMAZING though. She is the best FA I have had in many years.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Never happened. Flight was delayed. Had to be re rojyed

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I was very happy with everything, thank you for the smooth flight ✈️

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

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

This was the best carrier, comfort, service, good food, on time experience on a long haul flight. New, clean, quiet, smooth aircraft!!!

Worst airline. Nine hours late. Checkin agent was not helpful at all.

Crazy and confusing check in process for connecting international flights. Extremely uncomfortable seats in economy, bad in flight service with useless attendants, 10 year old movie selection, inedible food + only 1 full meal for 12+ hours long flight - 2nd snack was a cold bun with 1 slice of tomato and 1 slice of cucumber; 3rd was 2 breads - 1 hot and 1 cold. Finally absolute bad information on arrival time - in flight suggested we will reach at 12 AM until last minute, when we landed it was 1:15 PM

The price for Premium Economy seats very competitive and ITA beat the big guys in terms of fair. However, seat comfort was below expectations. Movie selection was poor. Food - absolutely horrible!! I felt like a prisoner for 13 hours being fed cold damp rolls and room temp water. NOT what I expected for Premium Economy!!

Most importantly, got us there and back safely and on time. Seats in Prem Econ spacious enough and comfortable. But pulldown footrest on both flights inadequate/broken. Crew...mixed: a few were quite pleasant, others seemed disinterested. Food was underwhelming. Yes, I know it's just "airplane food", so dont expect much... but even United is doing better now, and BA more so. Would I fly ITA again...perhaps. Price diff was main selector this time, almost 1K LESS/person than UA. I'm naturally frugal -- For 2K I'll put up with some small inconveniences.

Flight attendant really had bad behavior.. yelled at people when she is trying to defend, to have favor w her people..!

Appreciated being met with a glass of sparkling wine - also the warm cleansing towel offered before the meal. The food was tasty!

Overbooked. They left a lot of passengers on the ground

Flight was on time, there were no issues. It was also direct to SFO. For an international flight, I call that a win.

It was Ok for Business class considering we paid almost $10K for two seats. Disappointing part was the $640 (RT) to reserve the seats prior to departure unlike other airlines that is complementary when buying business class seats. Would I use ITA to go to Europe on my next trip -NO.

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.
