A spokesperson for the Federal Aviation Administration later confirmed that the glitch, at an air traffic centre in Leesburg, Virginia, had been resolved. Planes would be able to take off normally by about 16:00 EDT (20:00 GMT), the FAA said.

Flight tracking service FlightAware reported that about 400 flights had been delayed or cancelled across affected airports.

The affected airports are among the busiest in the US, especially in the summer holiday months.

Among those hit by the glitch were Washington's Dulles International Airport and Reagan National Airport, as well as New York's LaGuardia and John F Kennedy International Airport.

The FAA said the problem is not believed to be caused by any accident or hacking.

According to the agency, the fault was with a computer system known as ERAM which is used at 20 air traffic control centres around the country that handle high-altitude air traffic.


The system was installed earlier this year but was already years behind schedule.

"The FAA is continuing its root cause analysis to determine what caused the problem and is working closely with the airlines to minimize impacts to travellers," the agency said in a statement.
