The budget carrier’s three-times weekly service from Luton got under way on Tuesday (2 July).
Flights will operate on Tuesdays, Thursdays and Saturdays, with one-way fares from £24.99pp.
Situated on the banks of the river Aura, Turku is a gateway to the Finnish Archipelago, comprising 50,000 islands.
The launch expands Wizz’s UK network to 98 routes to 27 countries from 10 airports.
Owain Jones, Wizz managing director, said it was the airline’s ambition to help travellers explore Europe’s “undiscovered gems”.
“Our direct route to Finland’s oldest city means people looking to travel to Turku can do so in one short flight,” he said.
