So far, up to 3 days of interruption, 650/720 flights cancelled. Even assuming smaller planes with ~200 passengers, a modest cost per day of $300 (nonrefundable hotel bookings, accom for stuck passengers, taxi fees, etc): 200×650×900 = 117,000,000 And I think this is an underestimate, because those passengers still have to fly eventually, possibly on other carriers. By the time it's done, could be $500M. I wonder if they have been asked to pay a ransom?
