Ethiopian Airlines chief executive officer Tewolde Gebremariam told The Associated Press that the company expects FAA approval within a few days.
The Boeing 787 Dreamliners have been grounded since January because of a risk of fire from the plane's lithium batteries.
United Airlines earlier this month put its grounded Boeing 787s back in its flight schedule. United has a 787 scheduled to fly starting May 31.
Boeing Co. has proposed a fix for the 787's batteries, but it needs approval from the FAA.
