They are running a domestic SFO-ORD roundtrip this schedule and I believe in April as well on the 747. 0835 SFO departure, 1605 ORD departure, though it has been consistently running 1-2 hours late.
On a side note, I saw one of the departures last week looks like it was dispatched with an altitude restricted bird, only made it up to FL290 for the trip from SFO to ORD. Made for a nice long scenic flight!
