If you want to go live in India, Dubai, or Tokyo, you could probably do it in 10-15 years. Emirates has 777 Captains that are under 40 years old. Probably have to take a risk and work for a relatively new carrier that is planning on rapid widebody growth. That is how the young guys got into the widebody Captain spots at Emirates so fast. Unless you get hired by a U.S. legacy before you are 35 years old, it probably won't happen here in the good old U.S.A.
