The disruptions to electronic systems initially reported at Brussels, Berlin's Brandenburg and London's Heathrow airports meant that only manual check-in and boarding was possible. ADVERTISEMENT"There was a cyberattack on Friday night 19 September against the service provider for the check-in and boarding systems affecting several European airports including Brussels Airport," said Brussels Airport in a statement, initially reporting a "large impact" on flight schedules. Airports said the issue centered around a provider of check-in and boarding systems - not airlines or the airports themselves. "These attacks often strike through the supply chain, exploiting third-party platforms that are used by multiple airlines and airports at once," she said.
