-after 4 min to 24 hours, call Delta to cancel the ticket sbd ask for a refund. Make sure to mention EC refund. (you can do this online, but its sometime a PITA to have everything credited correctly)
-the ticket itself will remain a pending charge and will disappear in a few days
-the EC charge will post in a day or two, as will the EC refund 'from Delta'
-within 3 days (or 2-3 weeks) you'll see a reimbursement by Amex
As a more recent data point for those who care, I can confirm that this technique still works -- just did this in August 2014. And the timing noted by the OP is still valid.
Thanks OP!
