Airlines are beginning to cancel flights and get planes out of the way as Hurricane Irene barrels toward the U.S. East Coast.
    
The storm is likely to force hundreds of flights to be canceled through this weekend and create delays that could ripple across the country.
    
On Thursday, airlines offered passengers the option of free rebooking for trips to many East Coast cities.
