I'm in my third week of groundschool at Pinnacle and was already awarded MSP as my domicile. When we bid for our domicile on the first day they told us that most of us would go to DTW for at least a few months until our first choice opened up. So something between then and now has changed. Everyone else in my class got what they bid for too, most to MSP, some to DTW, and one or two to MEM. As far as upgrade time, 2-3 years is the average. They upgrade you as soon as you hit 3500 tt, or 3000 tt if the majority of it is at Pinnacle. Hope this helps.
