Belfast International Airport faced significant disruptions this morning as long security queues formed due to a staff shortage caused by illness. Passengers expressed frustration over potential flight misses on social media, describing the situation as chaotic. Airport management apologized for the delays and confirmed they are working with their security provider to implement contingency plans. Fortunately, security wait times have since returned to normal. Recent technology improvements aimed at expediting security checks had just been introduced, but were not enough to mitigate the staff shortages.
