TNOOZ: It took me about 15 years from when I started travelling for business and pleasure to appreciate the value of a professional travel agent.
In 1979 as a junior MadMan I relied upon secretaries and expense accounts for guidance, while personal travel was collaboration between an advertised special, a travel agency storefront, and my girlfriend.
By 1996 my prospering Internet development company was flying people around the globe and Ann Marie, our independent travel agent, made several dozen bookings a week seem trivial.
