Airlines begin canceling flights in earnest
Delta Air Lines is canceling 1,300 flights and will shut down at New York City-area airports on Sunday until Hurricane Irene passes.
With Delta's announcement Friday, airlines have canceled more than 2,400 flights through Monday.
JetBlue is dropping 880 flights, mostly in New York and Boston. American Airlines says it will cancel 265 on Saturday and probably more than that Sunday.
Irene is expected to make landfall around North Carolina on Saturday, move up the coast to New York on Sunday and then weaken in New England. It could strike major airports from Washington to Boston.
