What if Delta were more like Chick-fil-A?

Chick-fil-A and Delta. Two Atlanta based companies, just a few miles apart. Both started with excellence and values. One had major influence on the other (perhaps both on each other). Today, one has slipped from prominence, or at least from excellence. What happened?*

What if Delta behaved more like Chick-fil-A?

* A personal aside. I had an uncle who worked for Delta during their very early days, up through the late 60s when he retired as their VP of aircraft operations (approx title – his team took care of the aircraft). I don’t think that his departure was the key to Delta’s decline, but it is an interesting coincidence
