Currently on a MR. First leg was MCO-ATL-SEA-ANC, booked in V fare. Second leg was ANC-SEA-JFK booked in a K fare. About three weeks out I applied a swu and RUC to the respective tickets. There was upgrade space available on all legs (would ya look at that?!), tickets confirmed into Business class etc. Full seat selection, etc.

Go to check in for the first leg on app and I get an error message that I have no electronic ticket and to contact an agent. I call the DM line and a concerned agent has it reissued. Ok, reissues happen, odd, but nothing to be too concerned about.

Go to check in for the second leg, same thing! No electronic ticket. I tweet to DLAssist (as I'm on the MCO-ATL leg) and they respond "That's odd. Please allow me one moment to contact our reissue desk to see if they are able to help. Thanks *TD" check the app moments later and I can check in but I'm in coach! Back to the K fare, no SWU applied. Great. Call the DM line when I land and they proactively put me into business class again, as a J and F fare and say they'll "work it out later with the SWU's".

Underlying issue seems to be reissuing tix with certs. I was almost certain that when I was confirmed with the OP space available that they HAD reissued the ticket. The swu and RUC I used showed as "closed" in my delta. Any one have similar issues? Can't tell if this is a DL it error or if an agent coded my swu/RUC wrong maybe?
