In 2012 an Air France flight bound for Beirut diverted to Damascas and passengers were forced to come up with cash for additional fuel. The pilot couldn’t use a company credit card because of financial sanctions imposed on Syria.
So as insane as it sounds it’s not without precedent that passengers on a Star Alliance member LOT Polish Boeing 787 flight were asked to reach into their pockets to cover repair costs to the plane’s hydraulic pump before a Beijing to Warsaw journey could begin last Monday.
