I just got an email offer for a Virgin Atlantic World Elite mastercard, with 20K after first purchase, 25k after 2.5k spend within 90 days. 15k for minimum annual spend (7.5k after 15k, second 7.5k after 25k), and another 5k for adding two other card holders. Also, 3 miles per $1 on VA and 1.5 miles per $1 elsewhere.

What are thoughts on this? I did a search in this forum for Virgin Atlantic cards and didn't see anything so I thought I'd toss this up and see what you guys thought.
