Either way things go ca or fo you'll show up for the same class and seniority is awarded by age in any class so the oldest fo in the class would have a higher seniority the a younger street captain. One other thing there is a chance that if you were highered as a street ca that you may not go in the first available class as there may or may not be ca in line ahead of you. I don't know if their is a pool for ca but fo seem to go to class right away a few weeks after interview. Get in get your feet wet as an fo for a few months ask questions and then upgrade. Yeah there are a bunch of fo's on property that can't or don't want to upgrade due to atp mins, getting a full year's weather experience, or waiting for msp sf3 ca or 900 dtw mem ca. Dtw and mem saab ca are availabe to steet ca most of the time right now. New deliveries till sept at least, 2 per month on the 900 and still recieving the 200s till up to 17 we have 3 online. but the 200 are basically mostly staffed just backed up in training there. And as deliveries stop in sept the flow to northwest kicks in from 3 per month to 9 per month. So even if the fo's start upgrading there should still be plenty of movement for new fo's to upgrade in dtw of mem as saab ca. Flow agreement finalized by arbitrator yesturday.
