Skiing can get pricey, especially when you're staying in the city you're skiing in. However, with the help of airline miles, Airbnb and a local link for private lift ticket sales you'd be surprised how much you can save!
I'm a Delta snob and have the Amex card to build miles but I'm starting to fly with Southwest out of Vegas now, as well. Airbnb can get you a whole place like an apartment for less than what you would pay for a hotel room. Plus, you're usually supporting a private citizen, meaning you're buying local when you book your stay with Airbnb.
