The United States has lifted a ban on flights to and from Turkey following a failed coup in the country, the US Federal Aviation Administration (FAA) said on Monday.

The ban, which included both direct flights and those from a third country, went into effect after a faction of Turkey's military attempted to overthrow the Turkish government. The coup crumbled on Saturday as supporters of President Tayyip Erdogan took to the streets in defiance of the coup plotters.

The attempted coup forced airlines to cancel flights. Shares of Turkish Airlines had tumbled 12.6 per cent on Monday, logging their biggest one-day drop since 2013.

The FAA said in a statement that it lifted the restrictions at 1:45 p.m. EDT (1745 GMT). CNN Turk had previously reported the news.

In a statement, Turkish Airlines said its flights to the United States would resume on Tuesday morning.

The attempted coup followed a series of bombings that have hit Turkey this year, including a suicide attack in June that killed 45 people at Istanbul's main airport. They have weighed on international travel to the country.

As of July 2, international flight bookings to Istanbul for trips in the second half of the year were down 36 per cent from a year ago, travel data analysis company ForwardKeys said. – Reuters
