A series of bomb threats targeting passenger aircraft departing the UK has prompted emergency diversions, fighter jet interceptions and extensive security searches across Europe, disrupting flights operated by Ryanair, Wizz Air and LOT Polish Airlines.
Three UK-originating flights were affected between Monday the 2nd and Tuesday the 3rd of November, with aircraft diverted to alternative airports or subjected to precautionary security inspections following reports of potential explosive devices on board. The incidents involved flights departing London Luton, London Heathrow and Manchester, with emergency responses activated in Hungary, Poland and Spain.
Although searches of the aircraft involved have so far failed to identify any explosives, investigations are continuing to establish the origins of the threats and whether the separate incidents are connected.
Wizz Air flight from London diverted to Budapest
The first incident occurred on Monday the 2nd of November, when a Wizz Air flight travelling from London Luton to Sofia, Bulgaria, was diverted to Budapest following a bomb threat received during the flight. The aircraft was redirected towards Hungary, where a Hungarian Air Force Gripen fighter jet was scrambled to intercept and escort it to Budapest Liszt Ferenc International Airport.
Hungarian Defence Minister Romulusz Ruszin-Szendi confirmed that the fighter aircraft had been deployed within minutes to ensure the safe landing of the passenger aircraft.
Wizz Air confirmed the incident in a statement, saying: “Wizz Air confirms that today’s London Luton–Sofia flight was diverted to Budapest following a bomb threat received during the flight. The aircraft diverted and landed safely at Budapest Liszt Ferenc International Airport in accordance with the relevant security protocols and procedures, before taxiing to a designated stand, where the relevant authorities carried out the necessary security checks on the aircraft and passengers.”
The airline added that it was cooperating fully with the authorities and that the safety of passengers and crew remained its highest priority. Following inspections by the relevant authorities, Wizz Air confirmed that nothing had been found and the aircraft was able to continue its journey to Sofia.
Ryanair flight from Manchester prompts emergency response in Spain
A second incident occurred on Tuesday the 3rd of November, involving a Ryanair service travelling from Manchester to Murcia in south-eastern Spain. The aircraft, carrying 114 passengers and seven crew members, landed safely at Murcia International Airport at approximately 10.50am local time after a bomb threat was reported.
Spanish authorities immediately activated emergency security procedures, with the aircraft directed to an isolated area of the airport. Passengers and crew disembarked while specialist police officers and explosive ordnance disposal personnel inspected the aircraft. The response involved the Spanish National Police, Guardia Civil and specialist TEDAX explosive disposal teams, with a crisis committee also established at the airport.
Francisco Lucas, the Spanish Government’s Delegate in the Region of Murcia, confirmed the activation of security procedures, stating: “Security protocol activated due to a bomb threat on a flight from Manchester that has landed in Murcia. The 114 passengers and 7 crew members have disembarked and are undergoing a security check. At this time, the aircraft is being inspected.”
Following the inspection, Lucas confirmed that the Guardia Civil had ruled out the presence of explosives, adding: “The Guardia Civil has ruled out the presence of explosives on the plane from Manchester following its inspection.” Murcia International Airport subsequently resumed normal operations, although the investigation into the source of the threat remains a matter for the Spanish authorities.
LOT flight from Heathrow diverted to Warsaw-Modlin
The third UK-linked incident involved a LOT Polish Airlines Boeing 737 MAX operating flight LO286 from London Heathrow to Warsaw Chopin Airport. The aircraft, carrying 181 people, was diverted to Warsaw-Modlin Airport following information about a potential explosive device on board, landing safely at approximately 10.01am local time.
Passengers were taken off the aircraft as security inspections commenced, while the alert prompted a temporary suspension of operations at Warsaw-Modlin Airport. LOT confirmed that the aircraft had been subjected to a security inspection after the warning was received. In a statement, the airline said: “The aircraft security inspection has been completed, with no suspicious items found.”
Passengers were subsequently transported by coach to Warsaw Chopin Airport to continue their journeys. Warsaw-Modlin Airport later confirmed that the security alert had been resolved and normal operations had resumed.
Further threats reported across Europe
The three UK departures were not the only aircraft affected by security alerts during the period. On Tuesday, further threats were reported against flights arriving in Rome and Sofia, with two Ryanair services arriving at Rome Fiumicino Airport, one from Lisbon and another from Dublin, subjected to security searches following separate warnings. The Dublin service was escorted by Italian Air Force fighter aircraft before landing.
In Bulgaria, authorities also investigated threats involving flights arriving in Sofia from Milan Bergamo and Dublin, with the aircraft inspected by specialist security personnel. A further incident involved a Scandinavian Airlines flight from Copenhagen to Warsaw, which landed at Warsaw Chopin Airport before undergoing security checks. No explosives were reported to have been discovered aboard the aircraft involved in these incidents.
The latest developments follow a separate incident in October involving an Austrian Airlines flight from Tel Aviv to Vienna, which diverted to Sofia after receiving a bomb threat while flying over Romania.
Authorities investigating the source of the threats
While the immediate priority in each incident has been the safety of passengers and crew, investigators are also attempting to establish where the warnings originated and whether there is any connection between them. Bulgarian authorities have provided some of the clearest information about the developing investigation, with Lyubomir Nikolov, Acting Secretary General of Bulgaria’s Ministry of Interior, confirming that investigators were working to identify those responsible for sending the threats.
Nikolov acknowledged that the targeting of multiple airline services was becoming a particular concern, saying: “The unfortunate thing is that some airlines have now also started to be targeted, which means that aircraft have to change course and the relevant measures have to be taken.”
According to Bulgarian state broadcaster BNT, Nikolov also referred to previous investigations in which authorities had identified email addresses used to communicate threats and traced associated IP addresses to other European countries. However, investigators have not publicly established that the latest incidents originated from the same individuals or that they form part of a single coordinated operation. The Bulgarian official also indicated that there was no information at that stage pointing towards specific terrorist intentions or actions.
The distinction is important, as the circumstances surrounding the individual threats remain under investigation. While the concentration of incidents has raised questions about possible coordination, there has been no definitive public confirmation of a common source or an organised campaign.
Significant operational impact for European aviation
The incidents demonstrate the considerable operational consequences of security threats against commercial aircraft, even when subsequent inspections identify no suspicious devices. Aircraft diversions, emergency landings, passenger evacuations and airport closures all require substantial coordination between airlines, airport operators, police and national aviation authorities. The deployment of military aircraft in Hungary and Italy also illustrates the wider security response that can be triggered when a potential threat is reported against a passenger aircraft.
For airlines, such incidents can result in aircraft being taken out of service, disrupted flight schedules and passengers missing onward connections. For airports, the activation of security protocols can temporarily restrict operations and affect other scheduled services.
With investigations continuing in several European countries, authorities are yet to establish whether the latest threats share a common origin. For now, the confirmed position is that multiple aircraft have been targeted, several European airports have activated emergency procedures, and no explosives have been identified aboard the aircraft searched in the reported incidents. The safety of passengers and crew remains the overriding priority as investigations continue.
