The low-cost carrier boosted services after the Swiss government confirmed on Thursday (20 January) that pre-arrival testing would no longer required for vaccinated travellers from later this week.
Jet2.com said it was responding to “strong demand” from travellers wanting to head back to the slopes.
The news also follows the reopening of French borders to UK tourists last week and Jet2.com is set to restart flights to the French Alps this weekend.
Bookings have risen across all of the airline’s eight ski destinations of Chambery, Geneva, Grenoble, Innsbruck, Lyon, Salzburg, Turin and Barcelona (Andorra).
Steve Heapy, chief executive of Jet2.com and Jet2holidays said: "Skiers and snowboarders have missed out on the best part of two ski seasons over the past couple of years, so they are absolutely jumping at the opportunity to hit the slopes once again.
"All eight ski destinations that we have on sale this winter are looking extremely popular, and it is obvious that snow sports fans want to make the ski season last for as long as possible too.
"In response to that, we are expanding our Easter ski programme so that customers have even more choice when it comes to hitting the best slopes in Europe. With our ski flights restarting to France this weekend too, we are looking ahead to a very popular and successful ski season."
