NerdWallet recently earned a PhD in airline loyalty programs with a Frequent Flyer miles comparison chart.
Not only does it show you the relative value of miles programs (spoiler alert: Continental Airlines wins at 1.01 cents/mile, while US Airways brings up the rear with 0.46 cents/mile), but the winding chart also opines on baggage fees (JetBlue and Southwest: None) and the best airline credit cards.
According to the chart, Continental's Chase OnePass Plus Card is the most valuable one to own, with JetBlue bringing up the rear.
The chart is simply too big to reproduce here, so be sure to visit NerdWallet to see all the details.
