The crass UK media get it wrong again, deliberately. Virgin do not focus on holidaymakers, and the strike timing is therefore unrelated to the cheap holidays of the great British unwashed to Disneyland, etc. Any old lies to flog newspapers and gain attention.
Virgin do to a large extent focus on holiday makers. Look at how many 747s with 400+ pax they send to MCO at the weekend. Indeed, VS has been described as a holiday company with an airline attached.
Also, the press will always report (and sensationalise) stories like this through the impact on their own readers. That's their job. The impact on the business traveller flying at someone else's expense is of no concern to the press.
Not seeking to take any sides; just trying to explain.
I note from the FAQ on the Virgin website that they claim they will wet lease aircraft in the event of a strike. Where will they get these from?
