[Expired] Use This Promo Code To Save 20% on JetBlue Flights [Book by April 8]

JetBlue is back with another flash sale, offering 20% off flights if you book today or tomorrow — no later than April 8. With a new promo code, you can knock 20% off the airline’s base fares for travel between April 14 and May 20, giving you a nice discount on spring travel.

You’ll need to book quick to take advantage of these savings, so here is a full look all of the deals available to you.

JetBlue’s Spring Sale

This latest sale offers 20% off based fares from JetBlue, but you need to book by April 8, 2026, at 11:59 p.m. ET.

Eligible travel runs from April 14 to May 20, 2026, with this offer, but it only applies to flights on Tuesdays and Wednesdays. To lock in these savings, you need to use the promo code SPRING20 at the time of booking.

Unfortunately, this offer doesn’t apply to transatlantic flights to/from Europe, nor does it apply to Mint (business class), points & cash bookings, or connecting itineraries. Thus, the discount applies to nonstop flights within North America.

Here is a recap of the important terms:

• Book by April 8, 2026, at 11:59 p.m. ET.
• Travel on Tuesdays and Wednesdays from April 14 through May 20, 2026.
• The promotion is valid only for travel on Monday, Tuesday, and Sunday.
• The offer is redeemable only on jetblue.com.
• Eligible flights will be Blue Basic fares.

Is This a Good Deal?

Savings are savings. We love saving 20%.

Using the SPRING20 promo code, we found nonstop flights from Providence, Rhode Island (PVD) to West Palm Beach, Florida (PBI) for $70 in Blue Basic, $102 in Blue (main cabin), and $214 in EvenMore.

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

That same flight is available for 4,300 points in Blue Basic, 6,700 points in Blue, and 14,800 points in EvenMore — plus $5.60 in taxes, regardless of ticket type.

All of these options are providing above-average value for using points, using points at roughly 1.4 cents each. That’s avove our valuation of JetBlue points at 1.3 cents each.

Best Credit Cards To Book With

Since the most optimal option is to pay cash for your ticket, you’ll want to use a credit card that is rewarding 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.
• The JetBlue Card: 3 JetBlue points per $1 spent on JetBlue flight purchases with no annual fee.
• 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 across North America. To do so, use the promo code SPRING20, book by April 8, and then travel between April 14 and May 20 — but only on a Tuesday or Wednesday.
