Cem Kozlu

Cem Kozlu inherited a struggling state-owned carrier and delivered one of aviation's most consequential institutional transformations, setting Turkish Airlines on the path to flying to more countries than any other airline in the world. During his tenure in the late 1980s and early 1990s, Kozlu expanded the fleet from 24 to 67 aircraft—a 179% increase—and opened 30 new international routes, establishing the geographic ambition that would define the airline for decades. This expansion surpassed the growth of #2 on this list's venture during the same period, as it added only 15 routes. By embedding private-sector management discipline inside a state enterprise, he reduced chronic operational losses by 40% and built the foundation for a network that today spans more than 300 destinations serving over 90 million passengers annually. Kozlu subsequently served in the European Parliament and authored several books on leadership and globalization, channeling executive experience into public policy. Few Turkish business leaders have shaped a single institution so profoundly—or, through it, elevated an entire nation's global standing.
