Beginning on April 4, 2016, Austrian will begin service between Vienna and Shanghai, China.
As it stands now, OS will fly between the 2 cities 5 times a week and will use their 777 aircraft on the route. Flights will depart Vienna at 1:20p and will depart Shanghai at 10:50a (local times).
The outbound flight will be OS75 and will taken approximately 10 1/2 hours, while the return flight will be OS76 with a scheduled flight time of approximately 11 1/2 hours.
More accurate to say they’re resuming service to Shanghai. They dropped this route around 2007 if I recall correctly.
