That's according to two Obama administration officials who weren't authorized to comment publicly and requested anonymity.
The U.S. has been seeking permission for months for the U.S.-led coalition to use Incirlik as a launching pad. Turkey had been resistant to the idea amid domestic opposition. But in recent days, Turkey has been hit by a surge of violence blamed on IS-linked militants.
The officials say President Barack Obama and Turkish Prime Minister Recep Tayyip Erdogan (REH'-jehp TY'-ihp UR'-doh-wahn) discussed the plan during a phone call Wednesday.
The White House is declining to confirm the Incirlik agreement but says Obama and Erdogan discussed deepening cooperation in the fight against IS.
