A survey carried out by World Travel Market London found that 17% of holidaymakers were avoiding countries with a “high” terror threat while 12% said that they would not travel to destinations that had suffered a terrorist attack.

The study of 2,000 UK residents also found that 16% were so worried about the threat of terrorism that they had decided not to travel or had cancelled their holidays.

More positively, more than half of those surveyed (55%) said that recent terrorist attacks had not affected their willingness to travel.

But the majority of holidaymakers (58%) also said there was a “distinct lack of travel advice on where is safe to go”.

World Travel Market spokesperson Paul Nelson, commented: “With most capital cities on high alert, it’s hardly surprising that we are more cautious in our decision when it comes to holidays.

“However with Brits having such a strong desire to travel, I think its unlikely terrorism threats will be too detrimental to the resilient travel industry.”

The research also identified a surge in bookings in 2017 for destinations that are perceived to be “safer”, such as Greece, Spain, Italy and Portugal.

It also said that other countries such as Malta, Slovenia and Iceland were also set to benefit from this trend.
