A significant cyber-attack has resulted in multiple delays at Heathrow and other key European airports due to issues with an electronic check-in and baggage system.

The incident originated from a technical problem linked to software from Collins Aerospace, prompting Heathrow to issue warnings of potential delays. Brussels Airport confirmed that passengers were being manually checked in and boarded as a result of this disruption, with Berlin’s Brandenburg Airport reporting prolonged waiting times as well.

RTX, the parent company of Collins Aerospace, acknowledged awareness of the cyber-related disruption impacting various airports, stating they are actively working to resolve the issue. The affected Muse software is utilized for facilitating shared check-in desks and boarding gates among airlines, which led to significant operational setbacks.

Although British Airways has managed to maintain normal operations using backup systems, other airlines at Heathrow have found themselves in disarray, leading to hundreds of flight delays as tracked by FlightAware.

Passengers recounted their frustrating experiences: Lucy Spencer reported queuing for over two hours only to be told her mobile boarding passes were not functioning. Monazza Aslam lamented a lengthy wait on the tarmac waiting for news about her flight.

Despite the chaos, some travelers noted a degree of efficiency as staff worked to minimize delays. Heathrow emphasized that additional personnel were on site to assist passengers, advising them to stay updated on their flights and minimizing early arrivals.

The repercussions of the cyber-attack were visible at other airports, with Eurocontrol advising that flight schedules would be considerably altered due to the disruption. Dublin Airport also initiated a precautionary evacuation of Terminal 2 amidst ongoing safety concerns.

The origins of the cyber-attack remain unclear, with early speculation regarding potential ties to cybercriminal groups. Experts are monitoring the situation closely as authorities investigate the incident's implications for European aviation security.
