Cheapest way to fly to Whistler? and travel while there?

[sportschick4u@verizonenet]

I am going to Whistler Blackcomb in Dec and wanted to know the cheapest way to fly (ex. best airline or company). I am flying from the far east coast (virginia).

Also what is the best way to get from the Vancouver airport to Whistler? Ive looked on the web site but not sure how each ride (train, bus, car rental..) really is. For people who have been there should I rent a car?

Thanks
