Flights between Turkey and the US were suspended indefinitely on Saturday following a failed coup by the Turkish military on Friday night.
The U.S. Federal Aviation Administration has now prohibited all airlines from flying between the two countries in the wake of the putsch - in which at least 265 people were killed and almost 1,500 injured.
Nearly 3,000 suspected plotters of the coup have so far been arrested in the ensuing government crackdown.
Issuing the flight ban, the FAA said in a statement: "The FAA is monitoring the situation in Turkey in coordination with our partners in the State Department and the Department of Homeland Security and will update the restrictions as the situation evolves".
Nearly 1,700 military personnel have been sacked and 130 media outlets shut down as the crackdown continues following the failed coup.
The dispatch comes after President Erdogan called on US to hand over cleric Fethullah Gulen, who he blames for Turkey's failed coup.
Turkey has been warned of the consequences of imposing the death penalty as punishment to those involved in the failed coup attempt.
