UK Manchester airport and other UK airports were reportedly subject to a cyber incident, Sky News reports

Attribution is the first question in episodes of this kind, since past cyber incidents against UK transport infrastructure have spanned the full range from criminal ransomware groups to state-linked actors, and the official designation tends to drive whether the story stays an operational disruption or escalates into a diplomatic one. The established pattern is an initial period of conflicting detail, with the National Cyber Security Centre typically the body whose confirmation or framing sets the tone, followed by clarification of whether systems affected are passenger-facing or operationally critical. For markets, the historical transmission channel in comparable incidents has run through listed airport operators, airlines with exposure to the affected hubs, and insurers, while broader risk assets have tended to look through such events unless attribution points to a state sponsor. Where disruption has proven brief and confined to IT systems rather than air traffic control, flight cancellations have generally been recovered within days and the market read-through has faded quickly. The follow-ons worth noting are the scale of airport coverage beyond the initial report, any NCSC or government statement, and whether this coincides with other incidents, since clustering has in the past signalled coordinated campaigns rather than isolated criminal activity.
