She went to Japan for ARSION, JD Star, and Sun. And also had a stint in taiwan for AJP.
The only company with any money to fly her over is STarDom and as flik said, she has no ties there outside of Hailey and even that isn't anythign more than Hailey really loving their match in Canada and wanting a repeat. The only girls going to Japan right now are young girls who are willing to pay their flight for the experience. I suspect the only reason Del Rey went was one last hurrah before signing with WWE.
Shame though, as even though she's slown down a bit this year, she's still in the top 3 indy workers in north america going.
