Austrian Airlines is adding a fourth daily service between London Heathrow and Vienna from March.
The national carrier will deploy an extra Airbus A320 on the route from March 30.
New service OS461 will depart Vienna at 1245 and land at LHR at 1420 local time. Return flight OS462 will take-off from Heathrow at 1520 and arrive in Vienna at 1855.
The three other flights depart Vienna at 0700, 1715 and 2005 and land at Heathrow at 0825, 1840 and 2130 respectively. The return services leave LHR at 0600, 0915 and 1930 and arrive at Vienna at 0920, 1235 and 2245.
Austrian Airlines said in a statement: "The new route creates a range of additional transfer options, particularly to the Austrian provinces such as Innsbruck, Klagenfurt and Graz.
"Most importantly of all, however, it will create smoother links between London and Eastern Europe, and key centres such as Budapest, Sofia or Bucharest, than ever before."
