Air cargo companies conceded they were scrambling to cope. FedEx, the world's second-largest package-delivery company, started rerouting flights bound for Charles De Gaulle Airport in Paris. It also moved some packages by truck instead of air. Company spokesman Steve Barber could not specify what types of shipments were most affected. Although rare, flight problems caused by volcanic ash are not unheard of. The 1980 eruption of Mount St. Helens in Washington state grounded hundreds of flights for days. But ironically, the airlines' decision to reduce their schedules to ensure that planes are full could work against them as they scramble to find available seats on alternative flights. "These high-load factors can make disruptions like this into full-scale disasters
-- where passengers are stranded for days," Schwieterman said. "Ten years ago, the airline took just a few days to get back to normal. Now, it can take longer." Routing systems have also become highly sophisticated, with airlines planning the most efficient routes days and weeks in advance. "The system works great until there is irregular operation, and then everything unravels," Schwieterman said. "In situations like this, the efficiency of the system comes back to haunt them." A spokeswoman for American Airlines, Mary Frances Fagan, expressed confidence the company could deal successfully with the ash despite the cancellation of 34 flights to airports in London, Manchester, Brussels, Dublin and Paris by Thursday afternoon.
She said airlines are well-versed in dealing with air traffic disruptions caused by weather, hurricanes or even earthquakes. "Are there specific contingency plans for volcanic ash? I can't say there's a separate chapter in our crisis book, but we deal with Mother Nature day by day all the time," she said.
