Virgin Atlantic is 49% owned by Delta, and for all intents and purposes is essentially "Delta UK"
It is 51% owned by Branson (or an interest over which he has control), however. As a _very_ frequent Virgin Atlantic and Delta flyer, I can assure you there is nothing about Virgin Atlantic which approaches the terribleness that "Delta UK" implies.
He sold the majority of Virgin Australia many years ago (back when it was called Virgin Blue).
