Reuters reports:
Some of Europe’s biggest airports battled to restore normal operations on Sunday after hackers disrupted automatic check-in systems, with Brussels asking airlines to cancel half of Monday’s flight departures due to persistent problems.
Hackers on Friday targeted check-in and boarding systems provider Collins Aerospace, owned by RTX, disrupting operations at London’s Heathrow – Europe’s busiest airport, Berlin Airport and in Brussels.

The fourth airport was not named, but other media coverage identifies it as Dublin Airport.
