(I’m currently in Italy, our TV is tuned to BBC News and this was just presented as Breaking News…so this is preliminary and probably subject to updates/revision as more is learned about exactly what’s going on…)
BBC is reporting there is reportedly a “technical issue” at London Heathrow which has knocked out some computer systems at the airport (check-ins, baggage check are mentioned) and they’re warning of potential delays as they’re going to do this “manually”. They are also reporting similar issues at Brussels and Berlin, which some are describing as a cyber attack. The story mentions Collins Aerospace, a company that runs these systems, as a possible target. Details are sketchy right now, I’d expect more will become evident soon, but commentators are ominously referring to delays which would be expected to quickly grow if they have to manually check in passengers and baggage.
Maybe it’ll be nothing, maybe it’ll be a mess. If you are flying through LHR, BRU or BER (and possibly other European airports) today, best to check flight status and watch for any breaking news. Hopefully it turns out to be nothing. Good luck.
