As an avid traveler, I have a knack for the curious. Last evening, post work, I had a date with Google planning my next travel when my curiosity engulfed my thoughts. I was sitting at a café comparing flights and hotels for Cuba on my Mac. Fifteen years ago, I would have visited a travel agent, in town and would have been at the mercy of his/her mood. A self-service travel website was unheard of then, and the the physical travel agent desk, thankfully, has become obsolete now. What had led to the shift in how travel is planned and purchased?
