I’m in the same boat. Sent a few flight credit requests on 12/14 and most went through the normal process within 72 hours, but two included an Iberia leg and those didn’t process correctly. It auto-resubmitted them with a new ticket number (said “ticket exchanged, resubmitted with new ticket number”) and those still say “waiting review”. I’ve sent emails but they’ve stopped replying. In my case, this is key to unlocking my ability to redeem my 4,000 points so I’m frustrated. I tried calling but meeting services told me there was absolutely no way of contacting anyone who works in that department.
