Threats disrupted at least 18 European flights on Nov. 6

At least 18 flights across Europe were disrupted on Friday, Nov. 6, amid another round of bomb threats, The Guardian reported. EU transport commissioner Apostolos Tzitzikostas separately said 11 further threats against flights were reported that day, according to the Associated Press.

The figures describe different things: 11 is a count of reported threats, while 18 is a minimum count of disrupted flights. They are not competing estimates of the same total and should not be added together. Prague Airport reported nine flights threatened to or from the airport. Published accounts do not provide a single reconciled count or a common counting method. The flight figures also do not give a passenger tally.

That distinction matters because a threat may trigger a security response without each threat corresponding to one disrupted flight. The reports do not establish a one-to-one relationship between the two counts.

Threat reports earlier in the week i

EUROCONTROL was aware of threats against 14 flights on Thursday, Nov. 5, and seven on Tuesday, Nov. 3, the Associated Press reported. The Thursday count was twice Tuesday’s. On Thursday, nearly 26,300 flights operated across the European network; the 14 flights under threat were about 0.05% of that traffic, according to the AP report.

Using those rounded figures, that is roughly five flights under threat for every 10,000 flights in the network. The comparison provides a measure of scale against total traffic, not an assessment of the danger posed by any individual threat. Nor does it make Friday’s 11-threat figure a straightforward continuation of the earlier counts: that figure came from the commissioner, while the earlier numbers were EUROCONTROL’s count of flights it was aware of.

Responses included a diversion and fighter escorts i

The reported responses varied. A Wizz Air flight traveling from Prague to Rome diverted to Venice after a bomb alert, and passengers were evacuated after it landed, the Associated Press reported. Hungarian fighter jets escorted three passenger flights after threats. French authorities reported four threats against aircraft over France.

Czech police said security measures had minimal impact on normal operations at Prague Airport. At the time of the AP report, no suspicious items had been found and no one had been injured. Those details describe the situation reported then; they do not establish the outcome of every subsequent investigation.

Whether the threats were connected remained unresolved. Tzitzikostas said it was too early to determine whether threats against different aircraft were linked. The Irish government described the wider threats as likely a coordinated campaign of disruption, an assessment rather than confirmation of common authorship. Authorities had not attributed the threats to a group or state actor, and the AP reported no evidence linking them to a government.

Aviation-security experts were expected to meet in Brussels the following week to discuss responses, Tzitzikostas said.
