How will terror attacks affect travel and tourism?

For the second time in a year, the capital of the world’s leading tourist nation has been the scene of coordinated mass murders. The latest atrocity in Paris has traumatised the city and its people, and has profound implications for travellers. As security on all forms of transport is stepped up, tens of thousands of tourists and business travellers have been leaving the city.
In the longer term, the combined effect of the two massacres in Paris this year could change the face of tourism in the capital and beyond.
