Austrian Airlines has taken over the routes from Frankfurt to Graz, Salzburg and Innsbruck. Salzburg and Innsbruck have previously been served jointly with Lufthansa (on LH flight numbers), but now will be “purely” Austrian (OS) flights. Austrian is also considering taking over the routes between Frankfurt and Linz or Munich and Graz. The rotation between Vienna and Frankfurt or Munich will, however, continue to be served by Lufthansa.
