DUBLIN (AP) - It's taking a little longer to cross the Atlantic -- but at least the flights haven't been grounded again.
A cloud of volcanic ash from Iceland is now stretching more than 1,200 miles across the North Atlantic, forcing most flights between North America and Europe to divert south.
Hundreds of flights a day are having to carry extra fuel, because the diversions are lengthening flights by up to two hours.
U.S. and European airlines say they're taking it in stride, even though each extra hour in the air will meaning burning more than $5,000 worth of aviation fuel per plane.
American Airlines says its trans-Atlantic flights are traveling 90 minutes to two hours longer, on average. The airline says one flight to London had to be canceled because it wouldn't arrive before the airport's overnight curfew.
