Spokesman Martin Schaefer said there had been intense discussions between German and Turkish officials about the issue, which had threatened to jeopardize German participation in the so-called US coalition to fight Daesh (ISIL), according to Reuters.
"We are optimistic and hope and expect that all the desired visits by German lawmakers for Incirlik or other sites will be approved by Turkish officials," Schaefer told a regular government news conference.
"But we don't know that yet for certain."
Turkey had banned lawmakers from visiting the base in response to a June parliamentary vote declaring the 1915 massacre of Armenians by Ottoman forces a "genocide." German officials have said the resolution is not legally binding.
