JetBlue is offering a rare promo code sale, taking a page from ultra-low-cost carriers' playbook a week after agreeing to buy one

• JetBlue Airways is offering $25 off most one-way fares between September 7 and November 16.
• This is the first time the New York-based airline has offered discounts on fall travel.

JetBlue Airways is offering discounted tickets a week after announcing a merger with low-cost giant Spirit Airlines.

On Tuesday, New York-based JetBlue announced a two-day "The Get The Fall Rolling Sale" that gives customers $25 off one-way fares between September 7 and November 16, except on Fridays and Sundays. Tickets must be booked by 11:59 p.m. EST on Wednesday, August 3, using the promo code "FALLSALE."

The deal is valid on nonstop routes within the US, meaning Mint fares and transatlantic routes are excluded.

JetBlue told Insider that it has done promo code sales before, but this is the first time the carrier is offering a set dollar amount off for fall travel.

"Our past promotion code sales have been so well received by customers, we wanted to try one during a new travel period," Dave Clark, JetBlue's head of revenue and planning, told Insider.

The carrier's last big promotion was in November 2021, when it offered a promo code for $100 off roundtrip flights as part of a Cyber Monday sale.

The deal comes as ultra-low-cost carriers Frontier Airlines and Spirit Airlines promote similar offerings. Frontier recently slashed fares to as low as $19 right after Spirit said it would not be merging with the Denver-based airline.

Meanwhile, Spirit ran a one-day sale in early July that offered 70% off summer flights. The discount only applied to Tuesdays and Wednesdays.

Since the merger announcement, one of the biggest questions is how fares will be impacted. Henry Harteveldt, travel analyst and president of Atmosphere Research Group, told Insider that he believes Frontier remaining a standalone low-cost giant will put pressure on JetBlue to keep fares low.

"JetBlue could adapt certain pricing strategies that Spirit has been successful in using and apply those discount strategies to JetBlue flights, he told Insider. "So, it's possible JetBlue could become an even larger discount airline than it already is."

Harteveldt also said he is watching how JetBlue handles Spirit's $9 discount club, which gives customers access to lower-priced fares and other perks. According to Harteveldt, the program is successful.

"If the program works well for Spirit, then it may work well for JetBlue, and this is perhaps another way JetBlue could introduce more fare competition as it combines with Spirit," he said.
