One of the most effective tips for earning and redeeming JetBlue points is to leverage the JetBlue Plus Card, if you frequently fly with JetBlue. This credit card significantly enhances the rate at which you can accumulate points. For instance, you earn 6 points per dollar spent on JetBlue purchases, which is much higher than what you would earn through regular spending. Additionally, you also get 2 points per dollar on restaurant and grocery store purchases, and 1 point per dollar on all other purchases.
