A sudden shutdown of Delta Airlines computers, due to a "power outage", first caused the suspension of all flights of the American company and then sent the main international airports into a tailspin, including Malpensa and Fiumicino, due to the impossibility to check-in.
Despite Delta's reassurances, severe delays and many flight cancellations are expected. Very long queues in the major airports of the world. In many airports, check-in operations are carried out manually. No problem for planes that are already in the air.
