[Expired] JetBlue Flash Sale: 26% off Flights With Promo Code [Book by January 7]

JetBlue is running a flash sale, offering some attractively discounted flights to kick off the new year. However, you’ll need to act quickly, as the sale ends Wednesday, January 7.

Let’s take a look at the details to help you take advantage before this offer disappears.

JetBlue’s Kick Off 2026 Sale

JetBlue is offering a limited-time sale, with 26% off flights this winter using promo code GO26. And since JetBlue’s TrueBlue program works as a revenue-based points program, these deals also apply to flights booked using your TrueBlue points.

You must book by January 7, 2026, at 11:59 p.m. ET to secure this deal, with eligible travel dates between January 13 and February 28, 2026. However, there are some blackout dates to be aware of and Friday and Sunday travel is excluded from this sale.

Here are the important terms to be aware of:

• Book by January 7, 2026, at 11:59 p.m. EST.
• Travel between January 13 and February 28, 2026.
• The promotion applies for travel on most days except Fridays and Sundays.
• Discount applies to base fare, valid on nonstop flights only.
• Flights may be discounted if booked as part of a vacation package, but the other trip elements won’t be discounted.
• Blackout dates apply on January 19, 2026, and February 12 through February 23, 2026.
• Redeemable only on jetblue.com.

The discount applies to the base fare and is valid on nonstop flights only. The 26% savings can be found on Blue Basic, Blue, and Blue Extra fares, but EvenMore and Mint fares are excluded from the promotion.

Best Ways To Book

To take advantage of the savings, book before the end of the day on January 7, 2026.

If you’re paying cash for these tickets, we recommend paying with a card that rewards you for travel purchases. Here are a few of our favorite cards for JetBlue flyers — all of which offer big welcome bonuses and elevated earnings on flights:

• The JetBlue Plus Card, The JetBlue Business Card, and JetBlue Premier World Elite Mastercard^®: 6x JetBlue points per $1 spent on JetBlue flight purchases
• The JetBlue Card: 3x JetBlue points per $1 spent on JetBlue flight purchases
• Platinum Card^® from American Express: 5x Membership Rewards 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)
• Citi Strata Premier℠ Card: 3x ThankYou Points on air travel

Alternatively, you can book using TrueBlue points, though you should check the math to see what value you’re getting. We value JetBlue points at 1.3 cents apiece, so work to get something around that value if you’re paying with points for your flight.

Final Thoughts

If you’re looking to score a good deal, JetBlue’s current flash sale provides a great opportunity. You can score flights for this winter, but you’ll need to act quickly. The sale ends January 7 at 11:59 p.m. ET.
