Manchester Airport bosses have issued a warning to passengers due to depart this week.
It comes amid complaints from passengers who say they've had to wait in "two hour long" security queues. Many people have taken to social media to report the problems they've encountered, in a repeat of scenes from days and even weeks ago.
Earlier this month the airport issued a candid apology over its staffing crisis. A spokesperson for Manchester Airport said: “We apologise to any passengers in Terminal One who were affected by long waits at security yesterday afternoon. We are emerging from the most damaging two years in our history and, like several other UK airports, are facing resourcing challenges at present.
