Well the guys that got hired in march and April when we stopped hiring are on reserve still until the sept class starts to kick out. While I believe the ones we just hired in September by the time they get done will sit reserve maybe a month or two. Now there are 3 or 4 classes filled since the September 8th class so go figure. If hiring continues probably not more than 3-6 months depending on base and aircraft(msp tends to be senior). If hiring stops (not implying anything as hiring looks to continue) and you catch the last boat out of the pool... well you might be on reserve for a while. 900 movement is probably the fastest now but seniority rules for upgrade. 200 movement is the slowest right now but if hiring continues a lot of upgrades are going to come out of all FO positions.
FYI good or bad depending on your desired base the 200 is ONLY MSP based while the rest are spread across MSP DTW and MEM. And I have heard but cannot confirm they tend to give the 200 to people that desire MSP as a base. So as not to stick an east coaster or some one who desires DTW or MEM in a base they cannot bid out of till 2 years or up grade.
