@Kizzyjet @Lx_D While it may be true that Delta owns private jets, that's a Gulfstream 200.
DPJ only has the Challenger 300 and 604, Learjet 45XR, 60, and 75XR, the Citation Bravo, CJ2, CJ3, Soverign, X, and XLS+, the Falcon 2000 and 7X, a Phenom 300, the Gulfstream GIV-SP, G550, and G650, and a Hawker 800XP. In addition, Delta's Private Jets fly under their own code (DPJ) and callsign (Jet Card).
Looking at the FAA's registry, you can where the private jet came from:
The Gulfstream had that registration until 2014 when it was de-registered because it moved to Canada, and Delta subsequently reserved the registration for a 73J. That plane was only delivered last month, and as a result it's likely there are no pictures uploaded for it.
