Passenger check-in, security and baggage handling was affected by a power failure at Stansted this morning.
The airport said power had since been restored across a number of systems in the terminal.
“Power is now restored and our teams are working had to get systems back up and running as quickly as possible,” a statement said.
“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 in formation”.
The airport issued an apology for the “inconvenience and disruption” to journeys today amid reports of queues in the terminal.
