Airline reviews

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.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

How can you rate a flight when it is canceled after you leave the gate & 3 hours into sitting there or in remote area of airport after mechanical problems

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

Everything was great except for one thing. I was sitting in seat 1L with plenty of windows. Because we couldn’t sit next to each other, my husband was in 2L with only one window that he had to almost turnhis neck around to look out. Therefore, the window position with 1/2 of the “window” seats in business class is not optimal

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

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!!!

The plane was clean and the staff courteous and professional. The seat bottom was uncomfortable but only after many hours. It had a pressure point that left me a small bruise on my right leg (very surprising). The pasta was terrible (hard on the edges sticking out and soggy on the bottom edges) but I guess that's how it comes out in a microwave (?). The entertainment was glitching and shutting off every 20 minutes or so but, in the end, we made it home safely with very little turbulence and that's what really matters.

Would never fly lauffthabsa again. Seats were way too crowded together....very uncomfortable le

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.
