Count every bag
Skis, boots and ordinary luggage can be charged differently.
Weight and dimensions matter
Sports-bag acceptance does not mean unlimited weight.
Consider renting
Destination rental can be cheaper than baggage fees on a short trip.
Keep essentials in carry-on where allowed
Medication, documents and a basic change of clothing should not depend entirely on checked sports baggage.
General vacation planning only. Skiing and snowboarding involve risk. Use terrain within your ability, obey closures and resort rules, and use qualified instruction. Backcountry or off-piste travel is outside this site's instructional scope.
