Austrian Airlines will launch Vienna-Chicago service on May 17, operating five flights a week with Boeing 767 aircraft.
The airline most recently served Chicago in 2008.
Austrian expects that 70% of passengers on the Chicago-Vienna flight will transfer to flights headed elsewhere in Europe, particularly cities in Eastern and Central Europe such as Prague, Czech Republic; Bucharest, Romania; Sofia, Bulgaria; Belgrade, Serbia; and Skopje, Macedonia.
From Chicago, Austrian will offer connections to several U.S. cities via transatlantic partner United Airlines.
Austrian, an airline that is part of the Lufthansa Group, currently operates daily flights to New York, Washington Dulles and Toronto.
