Over vacation week, I took my son on a grand vacation to Ireland. It was a week of castles, forts, churches and a whole lot of green fields and sheep. The trip was also an opportunity to dig deep to pull up those kernels of knowledge gleaned from various books read over the years. My son kept saying, “But how do you know that?” My answer – I read about it once.

Spirit Airlines is at it again — first denying a dying war veteran a ticket refund, then announcing it would raise its fee for carrying a bag on its flight to $100. Passengers are outraged. A Facebook petition to boycott the carrier is gaining momentum. Under pressure, I interviewed Spirit Airlines' CEO.
