Figures. As long as Delta continues to assume ATL is the center of the world, they will have these kinds of issues like always requiring the pilots to "call home" rather than just give them the tools they need to finish the job on the spot.
The ATL-centric attitude extends far beyond what is essentially a domestic FF program with next to no focus on any international markets (still waiting for global FF redemption charts, you know the same ones NW had for years but were taken down and not replaced once the merger happened).
