Don't have to get rid of the contract, they could just enter an agreement with the union for a one time deal, the same way that they have done in the past for various things. We know this, AMR has an agenda but they ain't spilling the beans until they are ready to! Here is another speculation, look how AMR is calling the contract "next generation". One would think they are referring to a B scale for the smaller narrow body, in other words AMR will create and LCC within a legacy, the regionals have served their time and are becoming expensive to operate, look at Pinnacle, Mesa, Republic and ASA/Express Jet without SKW financial backing. 50 Seaters will not be replaced by 70 seaters they will be replaced by narrow body aircraft with less frequency. If you don't think this is a possibility look at the last contract offered to the AA pilots, look at the new aircraft order and look at what they are/aren't doing with Eagle.
