I've done it for two days. Flew up Saturday, came home Sunday. Was really rough on the body with all the traveling, skiing, and immediate altitude adjustment in Colorado (going from 500 to 11000+ feet in a few hours will fuck you up hard). Denver is probably the cheapest city to fly to. I did it for a sweet price ($300 per person after splitting three ways- 2 lift tickets, flight, hotel, and car. It would have been even cheaper if we stayed in an airbnb.). Lift tickets are the issue because the earlier you buy, the cheaper obviously.
Don't forget about delayed and cancelled flights. If you have a connection through Chicago, and they have bad rain or snow, kiss your trip goodbye. Also if your ski bag gets lost or delayed, forget skiing that day. Our bags didn't get loaded and arrived 7 hours late. If that does happen, ask for reimbursement. Airlines will give you vouchers for rentals and lift tickets and also gave us cash vouchers for future travel. Also consider the possibility of a line at the rental car facility. I've waited over an hour before in line. Best to fly in earlier than you need to. Tip: ALWAYS bring your boots on the plane. It can be your personal item. That way if your skis get lost, at least you won't be in rental boots.
Im right with you on this powder craze. The East Coast is all melting and the west is getting blitzed. Shit I flew out of SLC the day before they got a huge snowstorm. Then my flight got delayed by a day in Chicago. So pissed. Could have just stayed and skied.
