Bomb Threats Hit a Dozen-Plus European Flights in One Week

More than a dozen aircraft across Europe have been targeted by bomb threats since Tuesday, with no explosives found and no one claiming responsibility. The alerts kept coming on Friday, hitting flights operated by Ryanair Holdings Plc, Wizz Air Holdings Plc and Romania's Tarom, according to the airlines and authorities.

Wizz Air's flight from Prague to Rome diverted to Vienna, a spokesman for the carrier said. France logged four bomb threats against aircraft crossing its airspace on Friday alone, per the Prime Minister's office. Czech police reported that several aircraft departing from and arriving at Prague Airport received warnings about explosives onboard.

The surge began Tuesday and gained momentum Thursday. It lands on top of an already tense stretch for European security, with repeat drone incursions and hacking attacks on the rise across the continent.

What does this change for airlines and passengers?

Practically speaking, very little — and that's the point. A single email or phone call can upend the travel plans of hundreds of passengers, dispatch fighter jets and send police with sniffer dogs swarming a parked plane.

Luis Gallego, CEO of IAG SA, put it plainly to journalists on a call after the group's third-quarter results: "We cannot do anything else than to follow the strict procedures that we have. We always want to be prudent with all these issues."

His comment came even as the hoaxes increasingly look like copycat acts. Carriers can't risk treating any single threat as false. Ignoring one isn't an option either, as an Aer Lingus pilot discovered Thursday when he didn't immediately respond to a government request to land after a bomb call. The French military scrambled fighters to escort the plane, the Prime Minister's office said, and authorities are investigating.

'Coordinated in a way we haven't seen'

The breadth of targets stands out. Ryanair, Finnair Oyj, EasyJet Plc and LOT Polish Airlines all received threats, spanning the range from low-cost carriers to legacy airlines.

Ben Smith, CEO of Air France-KLM, told reporters Thursday: "To have this in a coordinated way, I don't think we've seen this before. It's unfortunate and we hope it won't give our consumers any reason to slow down or reduce their travel plan."

That last line is the commercial worry. European carriers have spent the year watching demand hold up through geopolitical shocks; a sustained wave of diversions and disrupted schedules is a different kind of threat, one aimed at traveler confidence rather than aircraft.

Why the system still holds

Bomb threats remain rare, and they almost always turn out to be false — a record that itself demonstrates how robust the sector's security standards are, according to the source reporting. Authorities across the continent are investigating the origin and circumstances of this week's warnings.

The protocol chain matters too. In the case of threats to some Wizz flights this week, authorities were notified first and then alerted the airline, which followed procedure, a Wizz spokesman said.

Nick Careen, senior vice president for operations, safety and security at the International Air Transport Association, sought to steady nerves: "Passengers should be assured that aviation security measures will continue to ensure the highest levels of public safety."

What comes next

With no claims of responsibility and investigations still open, the practical test for the industry is cost and repetition. Every false alarm burns diversion expenses, military scrambles and schedule slack — tolerable for a week, corrosive over a quarter. If the wave continues, expect carriers to lean harder on governments to trace the source, because the airlines themselves, as Gallego made clear, have no move available beyond strict compliance with the procedures they already run.
