Considering the challenge on either AA or US Air so much heartburn though as NWA/DL Gold barring unforseen circumstances I will fly enough to be Plat on one airline for the next 4 years in a row. Going to take test flights on both in the next 2 weeks, been so long I can't remember the pro's and con's of either airline. Delta is starting off on the wrong foot and this could be quite a change for me
