My interpretation came from my UAL roots. AA pretty much did the same thing IMHO.I thought you were refering to something like what I have heard AA had at one time with two completely different mechanic pay scales, hence A scale mechs, and B scale mechs made different top outs? anyway maybe we do have an "A/B" scale in some method of the term , just not my definition. All SWA mechs make the same amount based on years seniority.
Like I stated, it's not really important.
Take Care,
