So how much money does Virgin need that is an impossible question to answer, revenue has gone, summer trade won't happen and winter in normal times is lean so they will need cash to survive for one full year without much business, the question to ask is went do you think it will turn around and you start to see the business bounce back?, the difficulty for the government is if they don't give enough money to support the company then its waisted money, when thing turn BA will flood the market and grab what little business is around, RB and the exchequer need figure out an amount, impossible task as the virus will set the timeline, good luck for the future.
