JetBlue's program gives rewards called TrueBlue points. Joining the TrueBlue program is free and you can start earning points by booking flights online. Points do not expire.
You won't get a big sign-up bonus or a lot of perks, but you'll get three points per $1 spent on JetBlue purchases and two points per $1 at restaurants and eligible grocery stores. JetBlue Card will also give you a 50% discount on eligible in-flight purchases — other airline cards offer just 20% or 25% off.
As a reminder, TrueBlue points can be used on the flight, hotel and car portions of your flight + hotel package, excluding travel insurance, certain taxes and fees.
