Most of the crew members were rude, flight arrived late and we missed our connecting flight, they damaged my friends suitcase so badly that two wheels had been destroyed.

Loved the courtesy and punctuality. Very professional and most importantly on time.

My layover in Vienna was supposed to be 35 minutes but because my flight was canceled I had to wait in the airport for an additional 8 hours.

Very limited legroom in a 10 hour flight.very old plane.

The flight was delayed for 30 minutes with no apparent reason. There is no entertainment at all, and no USB or electric outlets for charging your phone or tablet.

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
