NEW YORK (AP) — Tens of thousands of flyers had their travel plans upended Friday after airlines canceled about 1,400 U.S. flights as thunderstorms hit the East Coast.
Another 6,300 flights had been delayed by early evening, according to tracking service FlightAware.
It was the second straight day of major disruptions and the worst day for cancellations since mid-June.
The three major airports in the New York City area and Reagan National Airport outside Washington, D.C., recorded the most cancellations.
American Airlines scrubbed about 250 flights, or 7% of its schedule. Republic Airways, which operates smaller planes for American Eagle, Delta Connection and United Express, canceled a similar number, about 25% of its flights.
Thunderstorms were stopping or delaying early-evening flights in New York, Boston, the Washington, D.C., area, Philadelphia, Baltimore and Denver, according to the Federal Aviation Administration.
About 1,200 U.S. flights were canceled Thursday, 4.6% of all those scheduled.
