I have just completed a call with Ms. Sandra Monroe at the Delta Manual Reissue desk. I needed to change a return flight from ATL-GIG that had a SWU, and cancel one domestic US fight while adding others, choosing the cheapest options I could while preserving Y-up and refundability. Such events are an ordinary part of my life, but nearly always I have given up on DL in teh apst because I could never get SWU's to make economic sense. Ms. Monroe not only understood my request first time out, a rare event with any carrier, but also clearly understood my objectives. She not only made the changes but also coordinated all the links and got everything correct the first time, even seat assignments. Kudos to Ms. Sandra Monroe, the Delta Manual reissue Desk and Delta. BTW, I am well aware that my usual experiences with changes have been far less happy. That makes me doubly pleased to have such an excellent and painless ticket change experience.
