More folks seem to want the -900. Sure, it's a nice plane, but seniority matters for both QOL and pay. A line on the -200 as an FO will blow the doors off any -900 on reserve. It's less than a dollar difference, which should become 1 rate eventually (sooner rather than later). Between breaking guarantee and Perdiem, and a few hotels vs a Crashpad will add up to a positive.

The -200 movement is faster than the -900 as the -200 is a growing fleet at the moment. DO NOT make a choice based on airframe. Anyone that wants the -900, will get to fly it once hired. Unless the NYC bases are your desire for QOL, the -200 will get you the most movement (positive) in Dtw and Msp. A line vs reserve is night and day. Movement is happening overall, but the sooner you hold a line, the more money and better QOL. That's the end result.
