Manchester Airport bosses have issued a fresh warning to passengers due to depart this weekend.
It comes amid continued travel disruption, with the airline industry struggling to bounce back from the coronavirus pandemic. Cabin crew from easyJet and Ryanair have agreed to strike on a number of days this summer.
Ryanair staff are planning industrial action in five European countries in June and July. Strikes are set to take place in France, Italy, Spain, Portugal and Belgium.
