Airline Computer Systems

Flights across the United States were affected by a technical glitch with a computer system in an unprecedented disruption on Wednesday.

US carrier Southwest Airlines grounded its flights on Tuesday due to a problem with its reservation system, the Federal Aviation Administration (FAA) said.

British Airways said its flights were returning to normal after passengers had to endure cancellations, delays and long queues at London airports as the airline suffered its third major computer failure in a little more than two years.

Amadeus, which operates global travel booking systems and offers check-in services for airlines, said it suffered a network problem on Thursday.

US President Donald Trump on Monday again rejected accusations that his ban on travelers from Muslim countries had prompted chaos in US airports, blaming protesters and a computer systems outage at Delta Airlines.

Delta Air Lines Inc said it was canceling more than 500 flights worldwide on Tuesday as the carrier worked to restore operations after a power outage hit its computer systems on Monday.

A computer system malfunction forced Japan's All Nippon Airways to cancel more than 100 domestic flights on Tuesday, affecting some 16,000 travellers, the carrier said.

American Airlines temporarily halted flights in and out of several of its major US hubs on Thursday due to a computer systems problem, officials said.

China-linked hackers have breached the computer systems of US airline company American Airline Group Inc and travel reservations platform provider Sabre Corp, Bloomberg reported, citing people familiar with the investigations.

Polish prosecutors are looking into whether the outage which grounded dozens of jets operated by Polish airline Lot at Warsaw's main airport on Sunday may have been caused by a computer system error, a spokesman for the Warsaw prosecutor's office said today.

Around 1,400 passengers of the Polish airline LOT were grounded at Warsaw's Chopin airport on Sunday after hackers attacked the airline ground computer systems used to issue flight plans, the company said.

Hackers and cyber-terrorists present an ever-evolving threat to airlines, with experts constantly testing for new vulnerabilities, including the fear that drones could be used to throw a plane off course.

In a shocking incident in the US, a computer security expert hacked into a plane's in-flight entertainment system and made the jet briefly fly sideways by ordering one of the engines to go into climb mode.

Several airlines are experiencing flight delays nationwide because of a problem with a computer system they use for services such as reservations, check-ins and online booking.

American Airlines said its computer systems were restored and flights had resumed after intermittent outages on Tuesday forced it to ground hundreds of US flights, but warned travellers to expect some cancellations to continue for a second day.
