Crystal will introduce new services from Bournemouth, East Midlands and Belfast to Innsbruck, a new Bristol-Kuusamo route, and two new routes from Newcastle to Chambery and Toulouse-Blagnac.
The routes open up resorts across Austria, the French Alps, Andorra, the Spanish Pyrenees and Finland's Kuusamo.
Tui-owned Crystal said the additions would create more regional sales opportunities for agents and spare their clients "longer journeys to larger airports".
The routes will be operated as follows:
– Belfast to Innsbruck, weekly from 20 December 2027 to 4 March 2028
– Bournemouth to Innsbruck, weekly from 20 December 2027 to 4 March 2028
– Bristol to Kuusamo, now on sale for winter 2027 and 2028
– East Midlands to Innsbruck, weekly from 20 December 2027 to 4 March 2028
– Newcastle to Toulouse-Blagnac, weekly from 19 December 2027 to 5 March 2028
– Newcastle to Chambery, weekly from 21 December 2027 to 1 April 2028
The new Innsbruck flights will serve resorts including Mayrhofen, Solden, Obergurgl and Seefeld, while Chambery opens up Meribel, Courchevel, Val d’Isere, Tignes and Les Menuires.
Flights to Toulouse-Blagnac, meanwhile, offer easier access to Soldeu, Pas de la Casa and Arinsal in Andorra, as well as Baqueira-Beret in Spain.
And besides Finland's Ruka ski area, flights to Kuusamo serve Finnish Lapland, allowing agents to offer extras like husky safaris, snowmobiling, reindeer sleigh rides, snowshoeing and Northern Lights experiences.
Scott Britton, Head of Crystal Ski Holidays, said: "These six new routes give our customers across the UK even more choice and flexibility when planning their trip, with convenient departures to some of Europe's most popular ski regions, including Austria's Tyrol, Kuusamo, the French Alps and the Pyrenees.
"For our trade partners, that means more options to match customers with the right holiday, while the convenience of having flights, accommodation, transfers and support wrapped into one package makes booking a ski holiday simpler than ever."
