Disruption continues at Heathrow, Brussels and Berlin airports after cyber-attack

Zaventem asks airlines to cancel half of Monday departures, while most of Heathrow flights expected to operate

Hundreds of thousands of passengers at Heathrow and Berlin airports faced flight delays on Sunday after a cyber-attack hit check-in desk software, while cancellations at Brussels airport suggested that disruption of Europe's air travel would continue into Monday.

Airlines were forced to revert to slower manual check-ins from Friday night after the attack hit Collins Aerospace, which provides check-in desk technology to various airlines.
