Turkish Airlines CEO Bilal Eksi said domestic flights would only operate to and from 14 big cities as of midnight Saturday. He said passengers would need to receive permission from the governor's office after 1400 GMT.
"As of Saturday 23:59, our domestic flights will be carried out from Istanbul Airport and Ankara Esenboga Airport," he wrote on Twitter, Reuters reported. Eksi added that flights would go to and from Ankara, Istanbul, Izmir, Samsun, Trabzon, Erzurum, Diyarbakir, Malatya, Van, Gaziantep, Konya, Adana, Antalya and Kayseri.

In a notice detailing the travel restrictions, the Interior Ministry said all citizens must remain in the cities they reside and would only be allowed to leave with a doctor's note, in the event of the death of a close family member or if they have no accommodation.
It said citizens need to apply to the Travel Permission Council, tied to the local governor's office, to travel. All bus terminals will be equipped with medical personnel to carry out regular checks on workers and passengers, it added.
