A major power outage hit Manchester Airport on Sunday, disrupting critical systems and causing significant delays in both domestic and international flights.

The outage affected boarding pass processing and baggage screening at some terminals, the airport authorities said in a statement.

Operations will resume soon, the authorities said, adding: “We are now in the process of resuming operations and expect flights to restart during the remainder of this afternoon and evening.”

Earlier, the airport authorities announced all flights from Terminals 1 and 2 are cancelled until further notice and advised passengers not to come to the airport.

Airport officials have warned of possible delays from Terminal 3, though flights are still operating.

"Passengers due to fly from Terminal 3 should come to the airport as normal unless advised otherwise by their airline but could be affected by delays," according to the announcement.

The airport authorities stated that some passengers' luggage may not be loaded onto departing planes, nonetheless: "We will work with airlines and handling partners to reunite affected passengers with their luggage as soon as possible."

Some arriving flights have been diverted to other airports, and people picking up passengers should check flight status before heading to the airport, the statement added.

It said flights scheduled for Monday are expected to be unaffected, and advised passengers to check with their airlines before travelling.
