Following security problems and threats of terrorism, the travel sector has had to “completely remix” its vacation destinations, reports CNBC quoting officials from one of Europe’s biggest tour operators.

In the recent years, concerns over security issues and terrorism have badly hit the tourism industry. Spain and the Caribbean have now become the preferred tourist destinations amongst tourists who have shifted from the erstwhile destinations such as Egypt and Turkey which have lost enormous amounts of visitors.

“This year we’ve been able to completely remix our holiday program from Turkey, Egypt, Tunisia, and taking 1.2 million bookings from there to Spain or other destinations… the Canaries [Islands] are up 27 percent, long-haul is up 40 percent, so there is a response that we’re managing,” Michael Healy, chief financial officer at Thomas Cook told CNBC on Thursday.

Following the terrorist attacks in Paris and Brussels in the past year, continental Europe has also not been spared from loss of tourism.

“Our Belgium business is significantly impacted. We will certainly make less money there this year,” said Healy.

Regarding holiday destinations, Thomas Cook would continue to adhere by U.K. government advice for tourists, Healy added.

“The U.K. government at the moment still does not allow any flights to Sharm [Sharm el-Sheikh] the airport there is closed. There are still some holidays being offered to Hurghada, that’s something that we take advice from government – it’s not something Thomas Cook does itself but you can be assured the welfare of our customers is very much at the forefront of our views,” Healy said.

Their first half revenue of $3.9 billion was announced by Thomas Cook on Thursday. Turkey – one of its most popular destinations last summer, have been shunted by tourists as the travel company reported summer bookings to be down 5 percent. Healy said that holiday prices in Turkey were down 15-20 percent.

The claims by the travel company were accentuated by the disappearance of EgyptAir flight MS804 en route to Cairo from Paris, early Thursday morning European time. The claims and results of Thomas Cook were announced in the immediate backdrop of this incident. The flight, which had 66 people on board, including crew is still untraceable and there is no official news on what happened.

There was fall of 18 percent in the shares of Thomas Cook on Thursday morning trading. The travel sector overall was down almost 1 percent.

Stating the possibility of a terrorist attack “without warning remains a concern,” specifically as Turkey marks Ataturk Memorial, Youth and Sports Day on Thursday, the U.S. embassy in Ankara – Turkey’s capital – issued a warning to American residents and tourists in the country on Thursday.

Foreign and US tourists should remain vigilant of demonstrations set for May 22 in Turkey and warned that “foreign and U.S. tourists have been explicitly targeted by international and indigenous terrorist organizations in the country”, the U.S. embassy also said.
