Data Point here. I had to cancel a DL Vacations trip that was redeemed during the double miles promotion last year. This past schedule change Saturday the flights went way out of whack making the trip impossible. It was a 7 night trip departing from PNS to ATL then the nonstop to HNL and back. Whole trip changed including an outbound connection in LAX which lost us our D1 seats and made our flight from PNS to ATL way after the ATL to LAX flight is leaving. I called today to cancel and was put on hold as the agent went to speak to a supervisor. When he came back he said that I would not be getting my miles back but would receive a credit for $6300 which was double the points exactly like I used for the promotion. I would also be getting the $557 refunded to my credit card. The flight credit expires Sept. 2021 is what I was told.
