Air France-KLM has announced that the fallout from the November Paris terror attacks, which left 130 people dead, cost the airline 70 million euros (US$76 million) in revenue in December, reports MarketWatch.

The Nov. 13 attacks in the French capital as well as the Oct. 31 downing of a Russian jetliner in Egypt have greatly impacted European airlines, with travellers cancelling flights amid enhanced security measures.

In addition to fewer expected bookings in November and December, Air France-KLM had to deal with a rise of hoax bomb threats, including the discovery of a fake bomb onboard a flight from Mauritius to Paris.

The airline did, however, report that business picked up in the second half of December, saying that “booking trends in December were in line with a progressive recovery.”
