Glad to hear you got the resolution you were looking for. Delta is notoriously resistant to reinstating upgrade certificates.
That’s disappointing to hear that Delta is enforcing the expiration date for confirmable upgrades reissued before the expiration date but flown after. I saved numerous GUCs from going to waste using that method. I suspect it’s still technically possible but that Delta has clarified its training / job aids to advise agents not to process these upgrades.
