BERLIN, Sept 22 (Reuters) - Operations at the Berlin

airport were still disrupted on Monday after a cyberattack over

the weekend knocked out passenger check-in systems, leading to

delays of over an hour for runners in town for the Berlin

Marathon who were trying to head home.

Hackers targeted check-in and boarding systems provider

Collins Aerospace, owned by RTX on Friday, disrupting

operations at London's Heathrow, Europe's busiest airport, as

well as in Brussels and Berlin.

More than 92,000 passengers were expected at Berlin airport

on Monday, more than the normal due to the marathon, said an

airport spokesperson, with work being done to keep disruptions

to a minimum.

Travellers should use their respective airline's online

check-in service if possible, added the spokesperson.

Collins said in a statement early Monday that it was working

with impacted airports and airline customers, and was in the

final stages of completing the updates needed to restore full

functionality.
