On Thursday, 5 November, several bomb threats affected air travel in Europe. According to news agencies, at least 27 passenger flights were disrupted. Some planes made emergency landings, and military jets escorted other flights as a safety measure. Airlines involved included Ryanair, Aer Lingus, Finnair, LOT, Aegean Airlines, and Wizz Air. For example, an Aer Lingus flight from Dublin to Rome landed at a French air base, where everyone left the plane so police could search for bombs.

The main reason for this situation was the bomb threats sent to airlines. These threats caused airports and airlines to follow strict safety rules. All crews and passengers were kept safe during the checks. Police searched the planes for any dangerous items, but they found nothing. Investigators did not know who sent the threats or if they were connected to earlier incidents in the week.

As a result, flights were delayed or changed to other airports, which caused problems for many travellers. However, there were no injuries and no explosives were found. Airports and airlines had to treat every threat seriously to protect passengers and workers.
