Is This a Good Deal?

Savings are savings. If you were planning to book a flight with JetBlue anyway, this promotion allows you to spend less than you otherwise would, and that’s always a good thing.

From the promotion page, you can input your flight details and see the savings automatically after putting in the promo code TREAT15. For example, we found flights between Fort Lauderdale (FLL) and Long Island (ISP) for $149.

And since JetBlue’s TrueBlue program is revenue-based, this promotional sale also applies to bookings using TrueBlue points.

All of these options are yielding above-average value for using points, offering roughly 1.5 cents each. That’s better than our valuation of JetBlue points at 1.3 cents each.

Best Credit Cards To Book With

If you’re paying cash for your ticket, you’ll want to use a credit card that rewards you for flight purchases.

Here are a few of the best cards for JetBlue flyers:

• The JetBlue Plus Card, The JetBlue Business Card, and JetBlue Premier World Elite Mastercard^®: 6 JetBlue points per $1 spent on JetBlue flight purchases, and perks like free checked bags, a rebate on inflight purchases, and more.

• Platinum Card^® from American Express: 5 points per $1 spent on flights booked directly with the airline or through AmexTravel.com (capped at $500,000 spent in purchases per calendar year, then 1x points).

Final Thoughts

JetBlue’s latest sale is a great opportunity to score discounted flights on upcoming travel with JetBlue. That said, you need to book by the end of the day today, October 28, to get these savings, and you need to travel between November and February.

If all of that sounds good, remember to use the promo code TREAT15 when searing for flights.
