JetBlue is offering 15% off select nonstop flights with promo code TREAT15, but you’ll need to book by 11:59 p.m. ET tonight, October 28, 2026, to take advantage.
This sale isn’t sticking around for long.
The discount applies to eligible Main and EvenMore fares for travel between November 2, 2026, and February 10, 2027, with a handful of restrictions.
How to Get 15% Off JetBlue Flights
To use the offer, head to JetBlue’s website, search for an eligible nonstop flight, and enter promo code TREAT15 when booking.
Here are the key terms to know:
- Book by: October 28, 2026, at 11:59 p.m. ET
- Travel dates: November 2, 2026 – February 10, 2027
- Discount: 15% off the base airfare, excluding taxes and fees
- Eligible fares: Main and EvenMore, including Base and Flex options
- Excluded travel days: Fridays and Sundays
- Blackout dates: November 19–30, December 17–January 4, and January 18
- Not eligible: Connecting flights, transatlantic flights, Mint, BlueFirst, award flights (see below), and Cash + Points bookings
The discount is valid for new bookings made directly through JetBlue and can’t be combined with other offers.
Keep in mind that the 15% discount only applies to the pre-tax fare, so your total savings will be a little less than 15% of the final ticket price.
What About Tickets Booked With Points?
JetBlue’s terms explicitly exclude award flights from the promotion. However, in our searches, we found that applying the promo code can also reduce the number of TrueBlue points needed for a flight.
That’s likely because JetBlue’s award prices generally track the cash price of a ticket. When the promo code reduces the cash fare, the points price may drop, too.
For example, a JetBlue flight between New York (JFK) and Boston (BOS) on December 1 costs $169 in Main, or 11,900 points without the promo code.
Applying TREAT15 brings the cash fare down to $146, or 10,100 points. That’s a savings of 1,800 points on the same flight.
If this sale piques your interest, don’t hesitate. It’ll end before you know it.
