The chief executive of Manchester Airports Group has apologised for the "disruption people have faced" and explained the reasons behind staff shortages and long queues.
In an open letter, Charlie Cornish said the group "had to cut costs just to survive" during the Covid-19 pandemic and that he expects around 250 new security staff to start in the operation by early May.
He also said the group "will be working hard to get passengers through the airport as quickly as we can over the coming weeks".
