If you read post #28, you'll note where I excluded the mechanics from the poorly paid characterization. The worthless union has proven particularly ineffective at raising mechanic pay at AA. The real disparity in pay is in the most expensive part, the pilots and the FAs. That's where US gets away with paying its E190 and A320 pilots less per hour than nonunion jetBlue pays its pilots.
Every single AA captain earns a higher hourly rate than any US captain. That's right - the most junior AA captain on an MD-80 earns a dollar more per hour than the most senior US A330 captain. AA's 737 pilots earn about $40/hr more than US East A320 pilots. If US pilots' earnings were equal to AA's pilots, that would cost US tens of millions of dollars, annually (if not over $100 million). US FAs average almost $10,000 less than US FAs, although Parker recently offered US FAs large raises that would have helped close the gap.
