What if you are 3 hours (south) door to parking IAD parking lot with no traffic? I know I want 756 eventually. I think I would like the schedule and destinations. I have a class date coming up soon. Should I just go 756 from the start and sit short call somewhere north of Richmond? How long before I would hold a line? Or go 737 initially and move over to the 756 when I have the senority to hold a line?
