JetBlue is expanding again at 
Fort Lauderdale-Hollywood International Airport. Just months after unveiling its biggest-ever schedule from the South Florida airport, it is adding more year-round service and more frequency in markets that are already showing strong demand.
In its latest announcement, the carrier said it would increase service to Cartagena, Dallas-Fort Worth and Tampa, while also making Jacksonville a daily year-round route, reinforcing its recently-acquired position as Fort Lauderdale’s number one airline. The latest move is part of a much broader build-up, which has resulted in JetBlue reshaping the competitive balance at FLL at a time when Spirit Airlines has been shrinking, and other low-cost rivals are trying to catch up.

JetBlue’s newest Fort Lauderdale expansion is not about flashy one-off launches. Instead, it is about making existing routes stronger. Cartagena will increase from four weekly flights to daily service from June 11, Jacksonville International Airport will become a daily year-round route from June 18, and both Dallas-Fort Worth and Tampa will rise from once-daily to twice-daily year-round service from June 18.

That matters because frequency growth is often more meaningful than simply adding another dot to the route map. More daily options make a route more attractive to local travelers, improve connectivity across the network, and signal that the airline sees staying power in the market rather than just a seasonal opportunity.
JetBlue framed the move as a response to what it is seeing on the ground in South Florida. Daniel Shurz, the airline’s senior vice president of network planning, said:
“These additions reflect the strength of demand we’re seeing in Fort Lauderdale and our continued commitment to building depth in our South Florida focus city. We are proud to continue investing in Fort Lauderdale with more year-round flying and added frequencies.”
The Climb To Number One At FLL

JetBlue’s claim to the throne as the new number one airline at Fort Lauderdale was not built on this announcement alone. In April 2025, it restored service to Philadelphia and Guayaquil, in July it added Atlanta, Austin, Norfolk and Tampa, in September it unveiled nine more routes from FLL, and earlier this year it added 
Orlando International Airport and year-round 
Dallas/Fort Worth International Airport service, while also increasing New York flying.

That wave of expansion helps explain the scale of the change. Looking at Cirium Diio data comparing the second quarter of last year (Q2 2026) to this year, JetBlue is set to operate more than 5,000 additional flights to and from FLL in Q2 2026, an increase of 45%. That equates to more than 180 daily flights at the airline’s South Florida focus city.
The key point is that JetBlue did not seize the top spot with one giant move. It got there in layers: restoring routes, adding new domestic links, building out its Caribbean and Latin American service, and then increasing frequencies once the network was in place and specific routes were showing higher-than-expected demand. That kind of cumulative growth is how airlines quietly change an airport’s pecking order.

FLL’s Low-Cost Hierarchy Is Being Rewritten

The broader story here is that Fort Lauderdale’s budget-airline structure is changing fast. Spirit, long the defining force at FLL, is down about 2,000 flights year-over-year in the year-over-year Q2 comparison, a decline of roughly 14%. That aligns with the airline’s prolonged financial and restructuring turmoil, and the resulting reductions to its fleet size, which has forced it to pull back capacity and reduce its footprint in some core markets.
JetBlue has been the clearest beneficiary, but it is not the only one moving in. Frontier Airlines has also expanded sharply, albeit from a low base, Allegiant Air has continued to grow selectively, and Breeze Airways has begun serving Fort Lauderdale for the first time. The result is that FLL is becoming less of a one-carrier low-cost stronghold and more of a fragmented battleground, with several airlines now trying to exploit openings created by Spirit’s retreat.

JetBlue’s march at Fort Lauderdale is certainly not finished. The carrier’s president, Marty St. George, recently said that the airline had “more stuff to come,” and explicitly tied JetBlue’s expansion to gate capacity opening up as Spirit pulled back, while FLL itself is also in the middle of adding a new Terminal 5. In other words, the runway for further growth is still there, and JetBlue’s rise to number one is not just a company story — it is evidence that FLL’s budget-carrier hierarchy is being rewritten in real time.
