Yes, it does. Patent # 7171369, "Method and system for providing dynamic and real-time air travel information." http://www.google.com/patents/US7171369

I have too much time on my hands tonight at Gate C6 waiting for a red-eye flight from SLC to ATL. I saw the small print patent number at the bottom of the screen, thanks to my brand new progressive bifocals. The real question is -- why did the patent office give Delta a patent for something so obvious?
