Hello everyone.

I am sitting at The Beat Live Conference in Nashville — one of the best conferences for the corporate travel management side of the house. The conference opened with a moment of silence in honor of those who lost their lives on 9/11.

As I always do each year, both here, and in PlaneBusiness Banter, I prefer to particularly remember those airline employees who lost their lives that day.

Yes, there were thousands of people who lost their lives that day. But for those of us who follow this industry, work in this industry, or simply continue to be fascinated by its endearing dysfunctionality, the loss of four airline crews that day hit us hard. And it still hurts.

This is our corner of the world. And as I see it, the courage and bravery of these crewmembers deserve our heartfelt acknowledgment. And remembrance.
