N class does earn miles according to the chart. Additionally, if the flight that you are on has a CO codeshare on it you will likely earn EQMs in addition to the 100% RDMs. The CO timetable show flight 8239 from LHR-SFO operated by VS, so there is a very good chance that you will get both EQM and RDM credit on your flight.

The main caveat is that VS flights earn zero elite bonus, so you on ly get base miles.
