The 175 in ORD is not the place to be like it used to be. I'm a little more than 2.5 years in and bid in the top 15% so my schedules are amazing... With that being said I'm taking the upgrade into the CRJ so that I can get some PIC and hopefully move on. I flew with a reserve Captain the other day who has been on reserve for 1.5 years and has less than 200 hours logged, that's not going to help your resume much. The growth for the plane looks like it's going everywhere but Chicago and the senior CRJ captains in ORD are transitioning over to the 175 keeping it perpetually senior. For those contemplating what to do you'll need to ask yourself what do you want?.... PIC, money, a specific schedule, depending on your answers to that you'll be able to determine which fleet and seat will suit you best.
