I was upgraded to business class due to my bid because accepted. EXTREMELY polite and friendly service. Decent seats and good food. Highly recommend it. If you can arrange to travel on a day when not very many business people are traveling (e.g., Wednesday) then you can possibly get an excellent seat at a great price.
