Just applied for the (targeted?) 80K offer (and was approved within about 30 seconds) which is effectively 60K, as I probably won't get the extra 15K and 5K for annual spend and and additional card users. But, spending $2,000 in three months should be easy enough.
I've never taken a paid flight on Virgin - just Upper Class rewards flights as a result of various bonuses and transferring of points from Chase and Amex when there are bonuses.
