PARIS (Reuters) – Paris airports have seen a reduction in traffic since the attacks that killed 130 people in the French capital this month, while security has been expanded, a senior executive said. “We are seeing an impact on traffic today, but it is too soon to say whether there is a longer-term trend,” said Edward Arkwright, finance director of Aeroports de Paris, which operates both Charles de Gaulle and Orly airports. He also said Paris airports had further strengthened security, already on high alert since shootings at a Paris magazine and kosher supermarket in January, following the attacks and had extended tests for liquid explosives to staff. Mid-November, which follows the end of a school break in France, usually brings a lull in traffic. Industry experts are focussing on whether demand driven away by the attacks, particularly from leisure travellers, will rebound during the normally busy Christmas and New Year season. “The period from mid-November to mid-February is generally the slackest period of the year, with the exception of the end-year holidays,” Arkwright told Reuters in an interview. Travel information firm ForwardKeys said on Tuesday that new flight bookings to Paris fell by 27 percent in the week following
