CA pay isn't based on what equipment you fly, it's based on your seniority. There were originally 3 pay bands when the concept originated with the BK TA- Pay Band A, B, and C. There is no longer an A pay band, only B and C. When you upgrade, you will be on the B pay rates. As of Oct 1st, the top 486 pilots on the seniority list are on the C pay band. As we take delivery of more 175s, the number of pilots on the C pay band actually grows somewhat. If you go onto the company into Flight Bid & Crew Info and look under Bidding Resources, you will see a link for CA Pay Rates. That link will show pay rates for "Small RJ", "Medium RJ" and "Large RJ". Small RJ rates are pay band B and Medium & Large RJ are pay band C. There are also links to see which CAs are on each pay band.
