Official figures for Rega rescues have yet to be announced, but a spokesperson told the Keystone-SDA news agency that helicopters and aircraft were called out at least 20,000 times in 2022.
Rega flew more than 2,000 operations in July alone to rescue injured people, the service said on Tuesday.
Air Zermatt declared 2022 as its busiest year since its inception in 1968, with some 2,100 missions beating the previous high of 2019 by 200 rescues.
Airborne paramedics were called out 82 times between December 24 last year and January 2. Its busiest day was December 28.
Air Glaciers also recorded an abnormally high number of missions. The rescue service usually averages around 2,500 flights per year but 2022 saw around 3,264 operations.
All services were kept busy during the ski season but also throughought the rest of the year as hikers and climbers took to the mountains.
