If you merge a regional with a mainline, if it wasn't a stable and DOH came into play somewhat, you would have to go to every pilot at the mainline and see how much time they had at a 121 carrier, because what if a 2007 hire at Delta had 15 years at ASA before going over to Delta? Would the 10 year CA at ASA go above the 2 year FO at Delta that had 15 prior years at ASA? I don't know if that would be that fair.
