Since Hurricane Harvey reached land in Texas, the ensuing flooding has forced the delay or cancellation of more than 12,000 flights across the U.S., mostly in hardest-hit Houston and nearby airports. From Saturday through Monday morning, the storm delayed 7,547 flights across the country and forced the cancellation of 4,539 flights, according to the monitoring site FlightAware.com. Harvey — which has dwindled into a tropical storm — has sent ripples throughout the nation’s air transport system. In 2012, Superstorm Sandy hit the East Coast, forcing the cancellation of more than 18,000 flights in a five-day period, with thousands of other flights delayed nationwide.
