For flight 793, on 12/20, Virgin America flight status shows it as departing LAX at 6:43 PM and arriving SEA at 11:04 PM. Of course, common sense would dictate that it does not take 4 hr 21 minutes to make that flight, and a check of flightaware reveals the flight did not actually land in SEA but instead flew all the way back to SFO and landed there instead. But, the VX site makes no mention of it being "diverted," still listing the arrival city as Seattle instead of San Francisco.

I noticed the same thing when a VX flight from JFK-LAX diverted to Iowa last month and was on the ground a few hours. No mention of the diversion on the VX site.
