I picked 5/2006 as it was the furthest date out that ticketing was available. I planned to travel in 6/2006. I had no idea of this conversion at the time of ticketing. Now it is creating some problems for me. I am under the impression that my tickets cannot be transfered back to miles since I converted them right before they were to expired.
