A wave of hoax bomb threats has upended air travel across Europe this week, hitting more than 50 flights departing from roughly a dozen countries on Tuesday, Thursday and Friday. Airlines have been forced to cancel, delay and divert services — and in some cases, fighters have scrambled to escort aircraft as a precaution.

None of the threats turned out to be real. But that hardly softens the disruption: when a threat arrives before takeoff, planes are evacuated and searched; when it comes mid-flight, aircraft divert and passengers can face hours on the ground. Every one has to be treated seriously, because the cost of ignoring a genuine threat would be catastrophic.

Who's behind it remains unclear. Some claim emails were signed off by "the fighters of the Male State," a far-right Russian nationalist movement founded in 2016 — though its founder has since denied any involvement on Telegram, saying the group hasn't existed since 2021. Another message sent to media outlets warned that "this is only the beginning," and threatened further disruption to European transport. The timing is telling: Ukrainian President Volodymyr Zelensky has been in Europe this week for meetings on the war with Russia, though investigators can't yet say how coordinated the campaign really is or whether copycats are piling on.

The practical problem for authorities is accountability. If the threats originate from a tech-savvy operation outside Europe, tracing and prosecuting those responsible is extremely difficult — which raises uncomfortable questions about how airlines and governments respond if the hoax waves keep coming. Ignoring them is a risk no one wants to take; treating them all as credible is expensive and exhausting.

For anyone flying in and out of Europe right now, the takeaway is simple: expect possible delays and diversions, build buffer time into any tight connections, and keep an eye on your airline's notifications. Hoax threats are, thankfully, almost never real — the far likelier impact on your trip is a delayed departure or an unplanned stop, not danger in the air. If you're travelling this week, it's worth checking your flight status before heading to the airport and knowing your rights around lengthy delays and rebooking.
