Aditya Ghosh
Age: 37
President, Indigo
40 Under 40 rank: 27
Ghosh knew nothing about the airline business when he took a job as general counsel for Indigo, then a fledgling low-cost airline in India, at age 28. But he impressed the airline's founders, who four years later gave him the top job. The Delhi native now heads the fastest-growing airline in the world's fastest-growing aviation market. The potential is huge, but Ghosh believes in pacing. And slowing down when it counts: He still finds time to take his 5-year-old son rock climbing on Sundays and to get his 4-year-old daughter dressed for school every morning. Here, Ghosh entertains Avantika (center) and Arunanshu (right) at Delhi's Bengali market.
