Asked to send Passport scan, and Skymiles card scan. I send the SkyMiles printable card PDF because Delta doesn't issue physical cards. They asked for a scan of my card again, with the SkyTeam ElitePlus logo. I sent a screenshot of my card in the Delta App. This was accepted. 4 months of Elite Status (Star Gold), extended to a total of 12 months if I fly one leg on Turkish Airlines.
