A recent analysis by The Wall Street Journal found that the November attacks in Paris significantly reduced tourism in France and throughout Europe.
Airline tickets to Paris and other European destinations have been canceled in large numbers, and hotel rates have dropped sharply. Travel to and within Europe fell noticeably, with Air France reporting an estimated $55 million revenue loss from November cancellations.
Holiday bookings for Paris during Christmas were down about 13 percent, despite a stronger U.S. dollar against the euro that had boosted trans-Atlantic travel earlier in the year. The article notes that Expedia saw Paris bookings increase by 30–35 percent in 2015, but those bookings dropped by roughly 40–45 percent after the November attacks.
Tourism to Paris has begun to recover, and that trend is expected to continue. Research by the World Travel and Tourism Council suggests the recovery could take on average about 13 months, though the WTTC anticipates Paris tourism will eventually return to pre-attack levels.
