I travelled to Beijing earlier this year via Ataturk with Turkish airlines.
3-4 days after my arrival in Beijing Ataturk airport was attacked by the 3 murderous suicide bombers, which shook me up a bit.
I have never stayed in Turkey, but can only say that the cabin crew on the flights were wonderful and I felt a great deal of sympathy for them. They were excellent ambassadors for their country, so much so that I even thought about visiting the country one day.
On the return journey I looked for signs of damage caused by the atrocity, but saw nothing. Security seemed to be at the same level as the outward journey.
A day later, back in blighty,and the reports of an attempted military coup made the news.
More tragedy, and this time by their own countrymen!
One day I may visit Turkey, but not for a while I think.
Incidentally I was working in Manchester some years ago when the 2 IRA bombs exploded. That rocked me, I can tell you.
Attacks can happen anywhere, but these days I try not to go near potential trouble spots.
