BA to put a sale on LHR - ABZ for a few months to convince VA to give up a Heathrow slot? Hmmmm
Or do you mean a sale on all long haul routes that they compete with Virgin to be discounted. VA still have hundreds of millions in cash, despite their appalling losses.
There may be convincing arguments that Virgin may not be with us by the end of the decade, but "a few months"?
