The business said the move came in response to "growing demand" for Lapland getaways after the 2020 Lapland season was wiped out by the Covid crisis.
Earlier this year, Santa’s Lapland also put its 2022 programme on sale early to allow families to plan even further in advance.
The brand’s 2021 season will offer three- and four-night departures from 26 November to 24 December, available on £150pp deposits.
Flights are available from Bournemouth, Bristol, Cardiff, Edinburgh, Glasgow, Leeds, Manchester, Newcastle and London.
Joe Ponte, chief executive of Santa’s Lapland parent Hotelplan UK, said: “Visiting Santa in his home, riding in a husky sleigh, elves, igloos, snow, reindeer, tandem skiing, tobogganing, spotting the northern lights and so on, all make for a pretty special Christmas. It’s the perfect antidote to help families rekindle the magic.
"As families have looked to secure that Christmas magic, new Santa’s Lapland bookings for 2021 have poured in. Combined with the high numbers of people who chose to rebook for 2021 after their 2020 trips were suspended, we’ve seen great numbers filling our 2021 programme. So much so, that we have added more seats from our regional airports to keep up with demand.”
Another Hotelplan brand, Inghams, put its winter 2022/23 trips on sale early last month following a "surge" in bookings for 2021/22.
