Austrian regional carrier InterSky has stationed an ATR 72 in Graz as it increases flight frequencies to Zurich.
The Friedrichshafen, Germany-based airline has thus far operated a 50-seat Bombardier Dash 8 Q300 on twice-daily return flights from Graz to Zurich.
But the airline wants to add another daily frequency on 31 March, deploying its 70-seat ATR 72-600 on the route from 1 June.
The ATR 72 is to be based in Graz.
InterSky received the first of two ATR 72s last month, with the second due to follow in March.
