Due to the aftermath of the botched coup in the Turkey, the United States of America has henceforth stopped all flights to and from Turkey. The Turkey’s national carrier, Turkish Airlines also has cancelled flights to the United States of America. This is according to the airline’s notice on its website. “All our flight operations (with the exception of the U.S.A. flights) have turned back to normal. Our flights to and from the U.S.A. on the 17th and 18th of July 2016 have been canceled and passengers booked on these flights are kindly asked to apply to our sales offices in city centers and respective travel agencies.”

This will definitely affects passengers all over the world connecting the airports in Turkey to the Northern America country.
Alternative for travellers is to use other airlines to the US as there is no definite time in sight for the Turkey-US route restoration.

“We extend our thanks to our passengers for their understanding and kindly ask them to follow our website for up to date information on their flights and booking.”-Turkish Airlines said.
