Nothing like coming back from vacation with a bang. That’s what I say. Yes, I am back from vacation and this week’s PlaneBusiness Banter will be posted tomorrow. (Sunday.) In the meantime, look what a little bird just dropped into my hand. A photo of what I believe is the new Southwest Airlines livery that will be unveiled Monday morning at the airline’s headquarters as part of its Media Day event. (Yes, I will be there.) As for where this came from, I’ll never tell. But don’t say I never do anything for you guys.
