Slovenian flag carrier Adria Airways is to start flying from Luton airport.
The Star Alliance member will run four flights a week to Ljubljana from the start of the summer flying schedule on March 25.
Flights are scheduled to depart from Luton on Wednesdays, Fridays and Saturdays at 9.45am and at 8.45pm on Sundays.
Airport managing director Glyn Jones said: “The launch of this Adria Airways service to Ljubljana with its convenient onward connections to more than 15 European cities and Balkan destinations such as Pristina, Tirana and Skopje is very exciting.”
