And Europe has 22,000 daily flights normally, 17,000 of them were cancelled Saturday. 17k flights times average number of passengers (100?) times average ticket cost ($100?) - it adds up to a lot of lost income. And as mentioned, the airlines were barely profitable as it were, and most of their costs are the same whether they are flying or not. Analysts are saying that many/most of the airlines in Europe will be bankrupt in a couple of weeks if nothing changes, some think we will be seeing the first bankruptcies within a few days.
