CHAOS has broken out at a major UK airport as a power outage brings operations to a halt.

Passengers hoping to fly from London Stansted Airport on Monday are being warned to expect lengthy delays when trying to board their flight.

Stansted was thrown into mayhem this morning when major systems, including check-in, security and baggage, stopped working.

Despite the power being restored, staff are still working to get the systems back up and running, say the airport.

Holidaymakers are being urged to arrive earlier as it’s taking “longer than usual” to get through the terminal.

Flights are operating as usual.

A spokesperson for the airport said: “Earlier this morning, we experienced a partial power outage in the terminal that affected a number of airport systems, including check-in, security and baggage.

“Power is now restored, and our teams are working hard to get systems back up and running as quickly as possible.

“However, it is taking slightly longer than usual for passengers to pass through the terminal while systems recover.

“Flights are operating as normal, but passengers are advised to allow plenty of time for their travel and check with their airline for the most up-to-date flight information.

“We apologise to passengers for the inconvenience and disruption to their journeys today.”
