The main thrust of posts by him and others might be summarized as "Delta Skymiles works for me and may work for you". In this vein, here's my tally on Skymiles, compared to AA and UA & CO for me:

1. Skymiles' low level awards TATL in Y (my current focus) are 60k, while AA is 40K and UA is 55. That makes Delta 50% higher than AA, offsetting most or all or more than all of the earning advantage (if any) Delta has.
