A late-night power failure at Heathrow’s main electrical sub-station on 27 November slashed runway capacity at the UK hub and prompted British Airways to cancel multiple Larnaca–Heathrow rotations on 28 November, including flights BA671/670. Passengers were rebooked via Gatwick, Manchester or long-haul connections, but premium-class and interline seats remain scarce as the holiday peak approaches.

Hermes Airports warns that aircraft and crews are out of position, meaning further disruption could spill into the weekend. Corporate mobility managers with Cyprus-based assignees who commute to London have been advised to monitor status updates hourly and consider routings via Athens, Vienna or Dubai. Freight forwarders report 24–48-hour delays for pharmaceuticals and tech components transiting Heathrow’s cargo centre.
Industry groups say the episode exposes Cyprus’ dependence on a single UK gateway; calls are growing for year-round services to regional British airports such as Birmingham and Bristol. Travel insurers remind travellers that EU261 compensation may not apply if the outage is deemed an “extraordinary circumstance”, though duty-of-care obligations still stand. Heathrow expects partial restoration of power by late Friday but has not guaranteed full capacity before Monday.
