Squaw also has a good deal about flying and getting a free lift ticket for that afternoon and night. I did that a couple of years ago as a "warmup" for the next few days.
Fly & Ski Free
Guests just off the airplane can ski or ride the afternoon and evening for free! Present a same-day commercial airline boarding pass with a matching photo ID at the Guest Services & Sales Center at Squaw Valley or Alpine Meadows and receive a complimentary lift ticket good from 1-4pm as well as night skiing, when night operations are in effect (Squaw Valley only).
Expect the unexpected and then deal with it.
