Delta announced that effective May 2016, it will no longer be flying between JFK and Istanbul. The carrier cites safety concerns in Turkey, including a travel warning issued by the State Department, and weaker demand for air travel to IST for its decision to end the service.

A search on Delta's website revealed that the change is already in effect, as nonstop flights between JFK and IST no longer appear — only those with stops in Paris (CDG), Amsterdam (AMS) or Rome (FCO) that are operated by Air France, KLM or Alitalia, respectively. Just last year, Delta announced that it was expanding its service to Istanbul with daily summer service between the two cities.
Currently, no other US-based airline offers nonstop service between the US and Istanbul. If you're still interested in visiting the city, you can fly nonstop on Turkish Airlines (a Star Alliance member) from New York (JFK), Atlanta (ATL; beginning May 16), Houston (IAH), Los Angeles (LAX), Chicago (ORD), Boston (BOS), Washington D.C. (IAD), Miami (MIA) and San Francisco (SFO).
