It's cat/class and longevity (which leads to relative seniority scenarios, but not directly).

So to set it correctly its:

Category/class (Widebody vs narrow body)
Longevity. (#1 NB CA at United has how many YOS? #1 CA at JB has how many YOS?) That's where the multiplier would come into play to give the additional YOS for UA (or any top 3 guys) some benefit before the JB guys get plugged in.

CA/FO mean nothing. The seniority list would be ghost bid so that each pilot would be placed where they COULD hold, not what they actually sit at the time of the merger.

So you're right, JB and UA aren't the same. Which is why there would be a fencing off of WBs before JB pilots would be integrated.
