American Airlines says flights are resuming after all services were grounded

Departure boards at major US airports show many American Airlines flights are delayed in the wake of the carrier’s technical problem.

At Ronald Reagan Airport in Washington DC, dozens of flights scheduled to leave between 06:00 (11:00 GMT) and noon were pushed back, with most delays lasting between one and two hours.

A flight to Dallas which was scheduled to leave at 06:30 departed at 08:16, while a 09:26 flight to the same city is delayed by almost two hours.

Most flights in the afternoon are departing on time.

Meanwhile, the departure times for local and international flights at Miami International Airport have also been delayed by up to two hours.

A flight to Barbados, scheduled to leave at 10:35 has been pushed to 12:15, for example

Several American Airlines flights at John F Kennedy International Airport in New York scheduled to leave in the morning were also delayed, including flights to San Francisco, Miami and Las Vegas.
