With the US legacies looking at upwards of 2000 new hires between now and 2015 and increasing every year thereafter, it provides movement and better T & C's worldwide into many places that were held by Americans who left for home. With the new contracts signed by DL. UAL and AMR and especially with emphasis on the quality of life improvements and soft money increases, staying in the sandpit would be foolish in my opinion unless you have skeletons in your closet, over ~45 or can't be hired by the legacies.
