During the flight, the fleas biting me in the plane.

Delay rushed to the next plane and bags didn’t arrive in chicago

Agents helping disable person doesnt know connections to Poland and after 9 agents helping and 2hours ,we made it to proper terminal. Polish Dreamliner its Polish nightmare liner with so narrow seats and no room under front seat for bag and feet,in economy class.To upgrade, to higher standart cost an arm and leg ,even there are empty seats No good experience overall

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

Checking in took very long for whatever reason. Flight comfort these days is always poor so… Crew was great thought!

The seats are small and the movie selection was disappointing. However, the food was excellent and the cabin crew was attentive and kind.

Bags lost no more to say, bad communication and no urgency to get it back to the hotel by the airline properly the worst airline I have used.

The customer service rep on chat refused carrying golf set at no charge that is customary for LOT and others. I wanted yo carry just ONE club not even full set! Web check in was nightmare. Most horrible lounge at warsaw. To call it business class is a BIG exaggeration. Rude staff warsaw to nyc. Seats uncomfortable and not flat as is now customary. Bad content and entertainment system.

Seats were so uncomfortable, my butt hurts so much, I wish they have more cushions,it really was horrible, Except that, Stewarts were polite food was decent

Plane is super outdated, seats not that comfortable for business class. Lounge also out dated. They need to catch up to 2024. Don’t think I’d ever fly again.

My flight was canceled and even though I paid אם KAYAK you didn't even answer me and obviously didn't refund my money. I will never buy a ticket through you again.

Accessibility serious problems in Viena airport making it seriousely difficult in in-between gates and boarding travel. Pretens of breakfast and service care in the economy pathetic.

One thing I really liked about Austrian Airlines was that the flight attendants were very kind, and the in-flight entertainment offered many choices. One thing that could be improved is the meal service, since only a vegetarian option was offered — it would be better to have at least two choices

One thing I really liked about Austrian Airlines was that the flight attendants were very kind, and the in-flight entertainment offered many choices. One thing that could be improved is the meal service, since only a vegetarian option was offered — it would be better to have at least two choices.

Despite the booked seats in front of the land we were moved to the back of the plane even first like 8 lines were totally without pasangers. When I tried to sit on empty seat flight attendant asked me to go to my dedicated seat in the fully crowded back of the plane. She was not able to explain why. Food was very poor on flight LAX - VIE.

We had a wonderful experience overall. The only issue was check-in our luggage at the Split Airport counter. It was very confusing because we needed to pay for baggage.

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!

Quick and organized boarding process, friendly staff but not as many snacks and drinks as the previous flight overnight

Landing was a little hard. Food was not great. No options.

I love this airline.God bless CAO and the whole staff of this company

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

I can’t even the whole trip was a catastrophe

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

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

All the flight to USA were arranged to E terminal whereas from Dubrovnik arriving on Zurich is on A80, have to walk all the way from A to E, even need transfer bus , for short transfer time like in an hour, we have to work fast, as soon as arrived at E, it is about time to boarding, pretty tight schedule, I hope Zurich airport can make some rearrangement so that transfer people do not have to walk long way. For short transfer time people, such as 50 min, this is even impossible if still like this.

When I needed to get my bag off of the plane so that I could take a train because the connection was 4 hours later, they took 2 hours to take my bag off making me take the train and miss my flight simultaneously. The seat size on the plane is too small for an average aged woman let alone a middle-aged man. It's unacceptable and I will not fly Boeing again.

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The biggest let down was with booking experience through Kayak. I booked a flight with checked bags on Kayak. Right away I got a message from travel agency that the flight is not confirmed and to call them. I called them and they said the flight I have booked is no longer available with the price I have booked it for and I can book it with about $100 more. I already had other options I could book with cheaper price so I asked them to cancel my booking. Then they said I can have the ticket with the same price but a date change which was not working for me as I had to be there for a seminar. So again I said no then they said they will cover the charges and confirm my flight. When comes time for check-in I see I have no checked bag option which means the travel agency deceived me saying I can have my booking as I had booked it. And at that point I ended up paying $155 for my checked bag going back and forth. I am extremely angry and unhappy with this experience
