Got this today. Will be interesting to see if anybody else follows suit. Seems like this would mostly kill off buying points. I didn't look to see if they are devaluing points at all when you do this method. The usual ratio is around 70pts = $1 cash for regular seats and 100pts = $1 cash for Mint seats. Pay for your flight with almost any combination of dollars and TrueBlue points—starting at just 500 points. Use Cash + Points for any JetBlue-operated flight, any time—with no blackout dates—just like when you pay for a flight with only TrueBlue points. The cash portion of your Cash + Points flight will earn TrueBlue points, so you can maximize your point-earning potential.
