Right, who knows.. however, Delta can limit the amount of numbers they take from Compass to whatever they want ( I know what the flowthrough says-- but real world actions are and most likely will be different-- its just how business works). They are
not going to put themselves in a shortage problem on the regional side of things. There is precedent here for many airlines in the past when hiring from their regionals. They dont shoot themselves in the foot.
But one thing is for sure... and that is "who knows". They could take all 90-ish ( or a % amount depending on the possible amount being hired).
I think Delta is planning to hire a few hundred...my guess is starting early next year.... I had a fortune teller read it from some grains of coffee!
But in the end... who knows.
