There is scope language that prevents any regional from replacing the DC9s once the cap is met on the mainline fleet. Also there are only 18 unaccounted for regional aircraft that can be purchased until mainline starts getting more aircraft. Not replacement jets net growth aircraft. I see alot of DAL guys conveniently forgetting about scope clause. I know its tough for DAL guys to understand scope language since they have a lack there of. Bottom line is Compass cant just replace all the flying the DC9s do.
