The indefinite ban took effect on Saturday in the wake of the failed coup attempt in Turkey that left 265 dead and over 2,000 injured.
"The FAA is monitoring the situation in Turkey in coordination with the State Department and the Department of Homeland Security and will update the restrictions as the situation evolves," the agency said in a statement.
The US embassy in Ankara issued a statement Saturday warning that US government officials have been told not to use the airport in Istanbul and that US citizens in the country should continue to seek shelter despite Turkey's claim that they have completely neutralized the attempted coup.
Pentagon press secretary, Peter Cook, said Saturday that US officials are working with Turkish officials to get permission to resume air operations as soon as possible following the attempted coup.
Cook acknowledged that US Central Command was forced to adjust flight operations in the anti-Daesh effort to minimize the effect of the Turkish airspace closure.
US authorities are also blocking access on and off the Incirlik air base where American nuclear weapons stockpiles are stored until the security situation subsides.
