EasyJet will fly twice a day, starting from 31 October, from London Gatwick to Rovaniemi on Wednesdays and Sundays.
It is expected that the new service will carry more than 13,000 customers in the first winter of operation.
Rovaniemi is the so-called 'official Hometown of Santa Claus' and has proved increasingly popular with British travellers over the past two winter seasons.
From 2016 to 2017, the number of British travellers to Rovaniemi grew by nearly 40%.
"British travellers are our traditional market," said Sanna Kärkkäinen, the CEO of Visit Rovaniemi. "We’re happy for the new connection that serves the visitors to meet Santa Claus and to experience the magic of Christmas any day at the Arctic Circle."
"The magical Northern Lights can be seen from August to April and there are many tours available. In winter season many travellers go on husky sleigh rides, reindeer farm visits, snowmobile safaris and skiing."
Meanwhile, Finnish airport operator Finavia is set to invest significantly in Lapland’s airports, and Rovaniemi Airport’s terminal will grow by 75% by the Christmas season of 2019.
