Delta Operated by Virgin Atlantic

Hi,
sorry if this is such an obvious question, but its important to me as my wife will *only* fly transatlantic with Virgin.
We are going to Orlando next year and have traditionally flown from Manchester, however, Glasgow is more convenient for us but has never had flights as late as Sept/Oct.
However, I now see I can get flights from Glasgow that are noted as "Delta operated by Virgin Atlantic"... Question is, does this mean its actually a Virgin plane with Virgin staff etc etc?
I need to be sure as basically, I could get to the airport and if turns out its not a Virgin plane my wife won't fly...
