On Tuesday, American Airlines faced a countrywide trouble with its computer systems. For this reason, the company was compelled to ground all of its flights for quite a few hours. The computer systems were restored by late afternoon. The operation of the company was also coming back to life slowly.
The trouble began about noontime and lasted until nearly 4:30 p.m. EST. The company had to cancel over 400 flights and delay scores more. It would have to continue with the cancellations and delays through the rest of Tuesday while trying to re-establish a regular schedule.
According to the company authority, the problem occurred due to the failure of accessing to the reservation system known as ‘Sabre’. Besides operating the bookings and reservations of the company, this system performs a number of flight related functions including online check-ins, tracking bags, ticketing, and printing boarding passes.
The company did not immediately show any clear reason of the problem. However, it confirmed that it was not related to the Monday’s Boston tragedy.
