Can you redeem virgin reward voucher on delta operated flight

[Tarah212]

Hello,

Struggling for availability to Las Vegas on ba or virgin right now and have a reward voucher which I intend to use for companion flight. I think the answer is no but can I use it on a delta operated flight which I can see comes up on the reward flight availability? I don’t want to hold to virgin for an hour plus unless I know! Thanks
