After facing increased disruption at security gates over the weekend, Manchester airport apologised to customers and admitted passengers’ experiences "fell below the standard we aim to provide".
"Our whole industry is facing staff shortages and recruitment challenges at present, after the most damaging two years in its history," an airport spokesperson said.
"The removal of all travel restrictions after two years, coupled with the start of the summer travel season, has seen a rapid increase in passenger numbers, which is putting an enormous strain on our operation."
