Terror forces travel industry to overhaul vacation destinations

Healy added that Thomas Cook would continue to adhere by U.K. government advice regarding holiday destinations.

"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 told CNBC.

Thomas Cook announced its first half revenue of $3.9 billion on Thursday. However, it reported summer bookings to be down 5 percent, specifically affected by tourists no longer traveling to Turkey – one of its most popular destinations last summer. Healy said that holiday prices in Turkey were down 15-20 percent.

The holiday company's results were announced on the day EgyptAir flight MS804 disappeared en route to Cairo from Paris, early Thursday morning European time. There is still no official news on what happened to the flight, which had 66 people on board, including crew.

Shares of Thomas Cook were down over 18 percent in morning trade Thursday. The travel sector overall was down almost 1 percent.

Also on Thursday, the U.S. embassy in Ankara - Turkey's capital - issued a warning to American residents and tourists in the country 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 also warned that "foreign and U.S. tourists have been explicitly targeted by international and indigenous terrorist organizations in Turkey" and should remain vigilant of demonstrations set for May 22 in the country.
