DOD upgrades have been reported to be open for purchase up to 30 hours before departure. They may, however, become available earlier upon request to Revenue Management and Pricing through the dedicated Travel Assistant team, a perk Ultimates enjoy regularly. Not clear to me whether or not non-Ultimates can access these seats more than 30 hours before departure, e.g., through the Platinum line, or just the Flying Blue line.
Yes, a polite request via the Platinum line does work as well. Only in KL/AF and ticket must be from either of those as well. So if the ticket has been bought on DL it will not work.
