Manchester Airport bosses have issued an immediate warning to all passengers after an IT failure on Tuesday.
A tweet from the airport's official account warns of disruption, though says there are "contingencies" in place. It said: "Manchester Airport is currently experiencing an IT system outage which is affecting some of our processes.
"We have contingencies in place and are working with our airlines and other partners to keep disruption to a minimum, and to get travellers through the airport as smoothly as possible. Staff are on hand in our terminals to support.
