Interesting, because the process I completed yesterday said it was cancelling my tickets and redepositing my miles. But today I did find the reservation under canceled tickets and repeated the process requesting refund - again I was asked if I wanted to cancel the ticket and redeposit the miles, I said yes, and this time it really did redeposit the miles.

I wonder what happened with the other tickets I canceled, because I didn't go through the Step 2 process yet those reservations don't appear under canceled tickets. It doesn't seem like I lost miles, but I can't find any record of them. One of them still has a single flight that shows up in my active itinerary list even though I canceled the reservation a long time ago (but cannot find any record of the cancellation anywhere.) When I click on the button for the receipt page I see it is gone though, it just shows the message: "We were unable to process your eTicket receipt". There is no "refund" option either but then again it doesn't appear I lost miles.
