United Airlines has just announce direct daily flights from LAX to Kelowna International Airport commencing Dec. 19.
From Kelowna, B.C. is it just under an hour to Big White, just over an hour to Silver Star, and about two and a half hour drive to Revelstoke or Sun Peaks. Sun Peaks can also be accessed via a shuttle flight to Kamloops followed by a three quarter hour drive.
These and other B.C. Interior ski resorts are way less crowded than most of the major resorts in North America. Even during the Christmas holidays I would describe these resorts as busy but not crowded and where an occasional 10 minute line up is considered a long wait.
