Question: how many miles do you need on jetblue for a free flight?
Answer: At a value of 1.4 cents per point, that means you could redeem a TrueBlue point for a minim of a $70 ticket. Or more accurately, you could redeem points for a cheaper ticket, though it would still cost you 5,000 points. JetBlue has recently changed that, and TrueBlue award redemptions now start at 3,500 points.
