Here's the real fraud. After years of railing against Delta (he'll remind you who invented the term "SkyPesos") and predicting doom for Delta (remember when the conversion to a revenue-based program would cost them customers "at the margin," a concept he uses but doesn't seem to understand), a fact that he had to acknowledge in his posts this past week demonstrates how little Delta has needed to listen to him: 1% of the US GDP is charged on Amex Delta cards.
A fact that both demonstrates his lack of influence on Delta and his inability to make accurate predictions about the impact on moves within loyalty programs on the airline industry as a whole.
