I think what forgot-to-bid is saying is E-175s at mainline for their mainline payrates. Doesn't the JPWA have an Embraer pay rate in it? Though it may be a little less than the -9, it is still way above what the rates are at Compass.

I believe the reason people only want Compass stapled is because it is represented by the MEC already, the pilots have a stronger flowthrough and flowback agreement (as opposed to Mesaba's where you guys can only flow back about a dozen pilots and they flow up at a much slower rate in a time of hiring), and the Compass fleet is tied to the mainline fleet (I can't remember how though).
