So she booked me on a KL flight.
After 5mins the ticket is reissued, and the validity of the ticket has been renewed to 30DEC13. It seems that I can make more changes later

Good news, I need two stopovers in AMS... Cannot find relevant general DL HIP rules though to refer to those if needed.
As for the validity extension if you are referring to NVA/NBV fields of a ticket, then in case it was manually reissued (which is likely the case, as the DL system seems to block the historic fare recalculation for RGN error fares) then it means nothing as I always get these filled in incorrectly. Though, you can possible argue with DL in case you really need as the ticket is a document.
