Ah I see, I checked there is a two-class Air Canada YVR-JFK nonstop at 14:20.
Hmm, then you'd need to get a Star Alliance Award. The redemption levels are the same. However, if you book business class JFK-LAX, you'd automatically get First class from LAX-YVR on UA and YVR-JFK on AC. That would be 40,000 miles.
Hope that helps.
