Air France-KLM said the November terrorist attacks in Paris led to a €70 million drop in revenues for December.
In a monthly passenger traffic update the airline outlined the “negative” impact the attacks had on bookings for last month.
It followed a €50 million drop in revenues for November, with flights to North America and Asia particularly affected.
Passenger numbers on Air France, KLM, and HOP! dropped 1.1 per cent to 6.2 million for December compared to the same period in 2015.
But once Dutch budget airline Transavia was included, total passenger numbers were "stable" at 6.7 million.
The airline said the decrease in bookings “significantly eased” during the last two weeks of December, suggesting a “progressive recovery”.
The attacks in Paris hit occupancy levels across the city. According to figures from hotel data specialists STR Global, occupancy across the city dropped almost 40 per cent a week on from the tragic event, compared to the same date in 2014.
