So we had two pay scales, an 'A' class one for the long term employees and a much lower 'B' class one for new starters. I thought about that for a while and about the fact that I only knew that Greenmont was in Tucson because of that note on the white board somebody had probably forgotten to wipe off. Then I thought about how I was carrying a bunch of FA's who probably had more years of service between them than any other four attendants on the airline. And right then I began to smell a dirty big rat. Like how come somebody had rostered all these high time 'A' gals on one flight? And like why Greenmont was sneaking down to Tucson before sun up?
