According to my calculations, at least by March or April, May to mid June 07 hires should be able to hold CRJ9 CA seat either in MEM or DTW. This is based on things staying the way they are today. I suspect MEM will remain relatively junior.
With the new merged list between DAL and NWA out, it does not look good for the flowthrough to resume in 2009. That means little or no attrition at the top.
