Delta has modified the criteria for its Delta Guaranteed Interview (DGI) program for pilots from their wholly-owned regional, Endeavor Air. It's still not a "flow" but appears to be an improvement including going back to look at some candidates who were previously unsuccessful. The full details have yet to appear on their website but I suppose this will improve recruiting a bit ?:
"Now, the pathway to Delta just got easier with program improvements that will give Endeavor pilots an even stronger advantage over Off-the-Street candidates for Delta pilot jobs."
