The reasons AA pilots want the merger are obvious:
-Increased pay rates (USAir management's better offer was used as leverage to lessen cuts in BK, and the future established pay rates are better.)
-Ability to be a truly global carrier and compete with DL and UA.
-More revenue = more ability to increase pay
-Merger MOU has language to establish new AA pilot pay on par with UAL and DAL in 2016. Alone, they can't do that.
-Larger route system, enormous Airbus fleet in future, improvements in trips/schedules, etc.
-Equity stake
The list goes on and on.
