Earning Tier Points on Delta Domestic flights.

Hi,
Before I go ahead and make this booking I thought it wise to check on here to make sure I haven’t got this wrong.
At the end of the year I will be in SFO for a whole day before travelling on to HNL (arrive on a Saturday afternoon before leaving for HNL on Monday morning). I read on here previously that flying Delta domestic First Class was a good way of earning tier points relatively cheaply. Previous posting I think mentioned going to LAS and back, however, I have just come up with the following:
SFO – LAX – SFO in First Class; the flight shows on Delta Airlines website as being operated by -
According to the Virgin website –
So am I correct in thinking that the flights above that are operated by “Compass Airline-DL Connection-DL Shuttle” qualify?
These flights should according to the Virgin website earn me 3 tier points per sector as the flights are less than 3,000 miles and will be flown in First Class.
If I have all this correct the return trip would earn me 6 tier points for the sum of £222. Much less than trying to earn the same on Little Red and with the benefit of doing it all in just two flights with only a few hours at LAX to kill.
If I’ve got this wrong please let me know.
Many thanks.
