Turkish Airlines is giving away few details on its discussions with fellow Star Alliance carrier Lufthansa regarding a possible partnership.
The carrier's chief executive, Temel Kotil, told Flightglobal at the Arab Air Carriers Organization annual meeting in Algiers that any potential tie-up was in its early stages.
"Talks are at a high level," he said, pointing to the preliminary discussions involving the German and Turkish governments.
He added that it was too early to suggest the form of any possible collaboration, and would not be drawn on whether this could involve any kind of cross-shareholding or be restricted to a simpler co-operation.
"We know one another well," Kotil said, alluding to the carriers' joint ownership of Antalya-based operator SunExpress.
Turkish Airlines has previously engaged in efforts to forge closer ties through investment in European carriers, without much success. It expressed interest in investing in Polish national airline LOT - before backing away - and taking a large share of Bosnian carrier B&H Airlines, until it withdrew earlier this year.
