Also from the press release:
As Virgin Atlantic aims to establish itself as the sustainability leader, it will fly only wide-body, twin-engine aircraft from London Heathrow and Manchester to the most popular destinations.
Suggests that sadly the game is up for B744 fleet.
More important than fleet mix, I have friends and ex-colleagues at VS and send best wishes to all at Virgin on such a tough day. I fear many others of us in the industry will be facing tough times in the weeks and months ahead
