So the "Delta wants 3 regionals carriers" rumor is around again? This was the saying going around a few years ago. Delta also wanted to not be in the wholly owned business anymore which is why they sold off Compass and Mesaba but couldn't get rid of Comair. But then they turned around and bought Pinnacle (now Endeavor) back to save their lift from going bankrupt. Around the same time, they bring in GoJet for some regional lift as well. So I would take these rumors with a grain of salt.
