Seven passenger aircraft across Europe underwent security inspections on 3 November 2026 following a series of suspected bomb threats. Two of the affected flights were operated by Ryanair and departed from the United Kingdom, while others originated from Ireland, Portugal, and other European hubs. Authorities in multiple countries are working together to determine if the incidents were part of a coordinated effort to disrupt airspace, although no official link has been established yet.

In Italy, two Ryanair flights arriving from Dublin and Lisbon were searched after landing at Rome's Fiumicino airport. Sources at the airport told the BBC that police bomb disposal experts carried out standard security protocols. The Dublin flight was escorted by the Italian Air Force until it landed. Inspections of the passengers, luggage, and aircraft interiors yielded negative results, and the alert was subsequently cleared.

Similar incidents occurred in Spain, Poland, and Bulgaria. A Ryanair flight from Manchester landed in Murcia, southern Spain, and was found to be free of explosives. In Poland, two flights heading to Warsaw were affected, including one from London Heathrow. The Heathrow flight was diverted from the main Chopin airport to the smaller Modlin airport, which was briefly closed. A separate Scandinavian Airlines flight from Copenhagen to Warsaw landed as planned.

Bulgarian Transport Minister Georgi Peev announced that bomb threats were received against two planes traveling to Sofia. The flights originated from Bergamo in northern Italy and Dublin in Ireland. Neither flight was diverted, and no explosives were found during checks. Bulgarian border police stated they received an email at 10:35 local time regarding a suspected improvised explosive device on a flight from Bergamo. The same email reported a similar threat against an aircraft arriving from Dublin. An operational headquarters involving various institutions was convened to manage the response.

The UK government described the incidents as malicious hoax threats. In a statement, officials noted that the country maintains one of the most robust aviation security systems in the world, with well-tested processes for dealing with potential threats. They emphasized their preparedness for situations like those observed on 3 November.

Aviation security expert Paul Mason noted that bomb threats on passenger planes are not frequent, making the recent cluster of incidents unusual. He suggested to BBC Radio 5 Live that the threats appeared credible and were made across a broad range of airlines. This pattern suggests a deliberate act by a specific actor rather than coincidental malicious calls. Mason explained that crews and ground staff must follow extensive processes to validate the credibility of such threats.

If the credibility of a threat reaches a certain level, a flight may be asked to divert. In some cases, the onboard crew is not informed of the specific details being handled by ground operators. Marco Chan, a senior lecturer in aviation operations at Kingston University and former pilot, stated that a bomb threat is considered genuine until it is resolved, even though most turn out to be hoaxes. Crews quietly search toilets, galleys, and storage areas, avoiding suspicious items unless they must be moved to a designated low-risk area on the aircraft.

Former airline pilot Terry Tozer, an aviation safety commentator, said the aircraft captain must assess multiple factors. These include the facilities available at the diversion airport and how the plane can continue its journey if the threat proves false. Once on the ground, the plane is generally taken to an isolated stand, passengers disembark, and police and bomb disposal teams conduct their search.

Passengers often remain unaware of the threat until after landing. Sarah, a passenger on the flight to Murcia, told BBC Radio 5 Live that the plane stopped suddenly and remained on the runway for about 30 minutes. Fire engines and a bomb squad arrived, and passengers were asked to evacuate. They were escorted by police and left behind all their belongings. Sarah said they were only later informed that it was an actual bomb threat against the plane itself.

The events follow a similar incident on 2 November, when a Wizz Air flight from London Luton made an emergency landing in Budapest. The flight was escorted by a Hungarian fighter jet after a bomb threat was reported. Wizz Air later confirmed that security checks were made and nothing was found.
