AMR will sell off 51% and keep 49% ownership. Fee for departure will change to 'code share' agreement to avoid SCOPE restrictions allowing Eagle to go for E190/195 types. Eagle will fly domestic and American will do long hauls, trans-cons, and international. The chances of selling to another regional (Republic, Skywest, etc.) is virtually zero. The last thing the majors want are 'super regional' carriers that can start dictating prices to them.
The end objective has always been to have Eagle do the vast majority of narrow body domestic flying and leave American with wide bodies only.
