Pros: "Plane was very clean and drink service was frequent."
Cons: "The gate was older, not well appointed and far from shops and better dining. We lined up only to be taken on a very long shuttle ride to the plane. I have had this experience before but in this case the planes location was virtually on the other side of the terminal. By the time all were boarded, the plane was late by about 15 minutes to takeoff, and we experienced more delay after that so that on arrival we were an hour delayed. Many missed connections in Vienna as a result. Crew seemed tense and on edge."

No option to pay for a second luggage; the company website very unclear about the luggage policy; no contact information as well as no web payment service; days before my flight, spent a lot of time and efforts to know that I could pay for a second luggage at the airport on my departure; 2. Paid $120 or so for the second luggage!!!??? After decades flying Austrian I will try switching to your competitors."
