Which Virgin Fare Class will guarantee me Delta Premium Select?

[astrodave]

Hi, very new here, so apologies if this has been answered. I'm looking to make a cash booking LAX-SYD one way on VA6551, operated by Delta (DL41). If I book Premium Economy for the VA flight number, how do I guarantee to be in Delta Premium Select, rather than Comfort+?

I've read how to do it with points via a Premium Reward flight booking, but I'm unsure how to do it with cash.

I can see both O & R available, will either of these place me in the Premium Select cabin (P)? And is there a simple table that shows me what VA fares translate to on DL?

Thanks for your help.

Premium select /C+ classes are P, A, G, W and S.

Great thanks, so where can I see if my VA fare code shows DL's Premium Select (P, A or G)?

For example, for this VA "O" fare code olwgwepd, what would the DL fare code be?

Cheers
