fwiw it's often said that seniority had no part in the straight RAW system, that's incorrect.

3 things from the old straight RAW system:

• When your RAW score equaled another pilots and you had the same number of days, the most junior pilot was up next. At the beginning of the month everyone had 0 RAW score so the senior pilot flew last.
• SC assignments were random in who did it and the quantity of pilots who sat SC.
• SC = 0 points. It meant nothing.

Now there were several senior pilots who had complaints about the old system and occasionally the complaints were based on it was unfair a guy only available for 3 days didn't get the 4-day trip that was assigned to them. That's still the case and would be the case on a seniority only based system.

Or that a senior guy with a RAW score of 1 point lower than a junior pilot gets a trip instead of the junior guy. But the line has to be drawn somewhere, I mean we assign seniority by your ssn and nobody complains.
