The carrier will resume services to Geneva, Grenoble, Salzburg, Innsbruck, Turin, Lyon and Barcelona from airports across the UK.
It will also offer a £1 ski carriage promotion, which is available on return flights to all of the destinations it offers.
Services to Chambery will operate from Birmingham, Bristol, Leeds Bradford, Stansted and Manchester airports for winter 2021/22.
The company’s ski programme also includes six other new routes, such as Geneva from Newcastle and Glasgow, Innsbruck from Bristol and Edinburgh, and Salzburg from Bristol and Newcastle.
Steve Heapy, chief executive of Jet2.com and Jet2holidays, said the companies’ ski flights are selling "very well" and predicts demand will increase.
"After missing out on the slopes last winter, we know skiers and snowboarders are really keen to head back to their favourite ski destinations, so we are delighted to be offering a fantastic programme of ski flights for Winter 21/22," he added.
"With a fantastic ski programme and promotion, there’s no better time to book early and ensure you get the best choice of flights and prices."
