Pre-boarding seemed tom happen at the same time as Business Class - I thought the idea was to allow people who needed extra time to board without interference from other boarding types, but I guess that's how they do it at LAX.

Pre-boarding seemed tom happen at the same time as Business Class - I thought the idea was to allow people who needed extra time to board without interference from other boarding types, but I guess that's how they do it at LAX.

The good: we liked fast boarding, the departure and arrival on-time. The not-so-good: The crew should learn from their sister-company Swiss with whom we took the flight to the US. Austrian onboard personnel need to smile more and provide a better service. Food was okay, there was the usual issue with “no more chicken” by the time they reach row X 😕. We did not understand why the crew collected trash so randomly and inadequately. We missed the free internet for messaging which was privided by Swiss as well. Hope this feedback helps.

They should be kind to the people Food is always plain pasta bread is from the fridge they don't even warm up Seat is so uncomfortable body hurts

Boarding by bus - this is 2026! Luggage did not board the plane though we had over two hours between flights. After it was located it didn’t fly immediately but waited one or two flights until boarding to fly yo Belgrade.

It was a great experience. The aircraft is a bit dated but other than that it was great.

Short flight. Bare bones and kinda seeming like an older plane. But got me there on time and that's what counts. Perfectly fine flight all the way from start to finish.

Austrian Airlines help and service was fine, but Kayak misled us into believing we had purchased a Business Class ticket. In fact, the tickets were only upgraded Coach Class tickets with luggage restrictions that belonged to the Coach Class. Very disappointed! Paid over $$$$ 9K for the two tickets. Very disappointing!

Leg room and seat back not a good recline (middle seat)

The restrictions regarding carry-on baggage is too strict. My wife was forced to check her carry-on bag. Never had this on other airlines.

Original Flight was cancelled Then Baggage was lost on rebooked flight

the glutenfree food was not more than ok. oatmel is not considererd 100% glutenfree, which you served me. I would expect a better meal

Checking in and crew were great. Seats in front of you in economy recline so much that you can't get out of your seat. I guess thats why its economy....

The flight attendants are amazing. The plane itself was not in good shape for passenger comfort. A good share of seat reclines were broken so they went back an unlimited amount, which meant the person in front of me was fully in my lap (the crew helped me find another seat but that would not have been possible on a full flight). Moisture from the ventilation was also dripping on me. And the entertainment system is almost impossible to hear.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

So disappointed, the flight from Zurich to Sarajevo was delayed for two hours for no reason, they were also shifting gate several times prior taking off

Flight was delayed, but otherwise it was a fine flight. Recommend boarding group by group, instead of calling up three groups at the same time

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

The issue is the flight is delayed, which causes me Missing the connecting flight by 3 mins. Remember the connecting flight is a US codeshare flight so UA should be able to inform the operating airline about the delay.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

The flight itself was ok, but one member of the crew was miserable

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

No white linens in premium economy . Salad was literally frozen. Food was terrible. No snacks. Ran out of food. I asked a flight attendant for snack on hour 8!of 16 hour flight and she said they don’t offer snacks and called me crazy for not having my own snacks for the flight.

I purchased a Polaris ticket. The plane did not have the lie flat seats - I was not notified. I actually can not believe they traded a dif plane and did not notify me or refund monies

It's not United, but TSA security at Terminal A in Newark is a disaster and seriously makes me consider switching to flying out of JFK. The touchless TSA pre-check had a line of over 50 people and the bag screening was so slow that it limited the flow of people through the facial recognition process. It is the only airport that I frequent that has this issue and makes me reconsider whether I should fly out of Newark given the wasted time and frustration it causes. As I said, it is not a United issue but will impact United if people choose to stop utilizing Newark airport because of the poor experience.

The employees seemed impatient with their guests. It seemed like they were giving us orders, instead of easily assisting. Our flight was delayed waiting on a flight attendant. It was alright.

We missed our connection flying back from the Middle Wast because we were misdirected by a United employee. We had purchased first class tickets, but had to need up taking a later flight that got us in to our destination at 1:00am after a long Internatinal flight and we had to sit in the back of the plane in cramped coach seats with little padding.

The flight was for my mom in wheelchair the staff in Newark wer not friendly took a long time to even get a wheelchair she almost missed her flight because they finally got a chair few minutes before boarding they had to rush her to the gate. They took her carryon and checked it as a bag told her don’t worry free of charge but they charge the credit card anyway. She also told me the seats are not comfortable at all as if they were broken she could feel the bars in the seat SFO staff was much better overall she had the worst experience

My premium economy experience did not live up to my minimum expectations. I've taken this flight twice in the last three weeks, and each experience was the same. The premium economy seat was worn and extremely difficult to recline. It took two people to return it to its takeoff and landing position. The food was OK, but for the premium that a premium economy seat cost, I expect a satisfying meal. Years ago, I looked forward to the experience of flying transatlantic on Lufthansa (I especially enjoy the hot towel before the meal), but this is not been my experience recently. I'm not going to use Lufthansa again.

They left a little late, contributing to our missed flight.

United did a good job of communicating before the flight, but a simple notice about the expected time for the completion of repairs to the broken navigation services (which closed the airport for the day) would’ve helped to clarify our expectations. With so many cancelled flights on the 21st of September, a little certainty about our own departure would’ve helped. Because of the disruption, the plane was quite empty, and at 6‘5“ I was able to steal a little extra legroom from the empty adjacent seat. However, I am still waiting for the day when I can sit in a standard economy seat and simply straighten my legs. Cabin crew were amazing. Great attitude, and moments of fun with passengers.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

I was deceived on the Kayak site expecting a ticket, but instead finding a "standby" reservation. When I tried to change the ticket, I paid almost twice the price of the original ticket. Then, the airline refused to give me the reserved seat I had chosen and paid for. I think I deserve a refund for this leg of my trip because I was doubly charged and did not receive what I had paid for. I put in a complaint with Lufthansa because the ticket was sold originally sold as a flight they listed. Someone here needs to take responsibility.

Excellent service; they helped me reschedule so I can fly in an earlier flight

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United
