The comparison between Mesaba and Comair post Ch11 is rather interesting. It makes you wonder why DL didn't beat Comair with the bat harder during CH11. Had they been as heavy handed with Comair as NWA was with Mesaba the whole picture could be very different.

Pre Ch11 both Comair and Mesaba were "expensive" feeders. During Ch11 Mesaba was gutted and Comair kicked around. Post Ch11 Mesaba is recouping their losses and "growing" back to pre Ch11 size. Post Ch11 Comair continues to shrink.
