Well... I admit I'm not as informed as RJ85FO (blinders really) but here goes. The Indoc Training is a new hires start date. Initial is for new hires after Indoc AND pilots switching planes. Move date is the date you start at your domicile. If you originally get MEM in training. You want detroit (set it up on mymesaba). After you are awarded Detroit this will be the date you start there.
