United Airlines and its passengers suffering at the hands of a computer “systems issue” today, that delayed and grounded more than 60 flights around the world. The exact cause of the computer glitch hasn’t been confirmed, but due to a spate of other computer problems affecting the airline industry recently, there are concerns it may be due to a hack.
Theairline tweetedit was aware of the problem and was working to resolve it, before sendinganother tweetat 3 a.m. ET claiming the problem had been cured, and flights would be returning to normal. United said only a small amount of flights were delayed, in a statement given toThe Independent.
Tweets sent during the outage showed mounting delays, including a Newark to Dublin flight due to depart at 10:25 p.m. still not leaving the airport until after 4:30 a.m. the next day. Many passengers affected by the computer outage tweeted using the hashtag#UnitedWeWait, but angry messages tailed off as United’s computer system recovered.
While there is no evidence of a hack causing the system malfunction, United’s problems follow several similar issues that have affected Delta Airlines and British Airways already this year. In September British Airways was forced to cancel hundreds of flights after a power outage took out its computer systems around the world. Delta also saidpower was to blamefor its 300 or more cancellations the month before. In a related incident around the same time, Vietnam Airlines had to stop passenger check-ins after itsflight information screenswere hacked, and politically motivated messages were shown.
Vietnam Airlines was obviously hacked, and hackers played havoc withEuropean airline Dot’s computersback in 2015; but what about the others? Following Delta’s problems in August, the CEO of computer disaster recovery company Continuity Software toldCNN Moneyairline computers fail and flights are canceled due to it for three reasons: Human error, no backup system being in place, or a hack. He notes the Delta outage was unlikely to be caused by a hack, due to the speed with which the issue was resolved. It’s likely to be a similar story with United Airlines, given there was just an hour between the tweet saying it was aware of the problem, to the one confirming it was resolved.
