With Spirit having shut down, the focus now shifts to what will happen to fill the void. Of course, Spirit had more capacity than the industry needs right now, so not all of it will be backfilled. But there is absolutely going to be movement in the airline’s three biggest markets: Fort Lauderdale, Detroit, and New York. Today, I want to look at Fort Lauderdale more closely.
Fort Lauderdale was Spirit’s home and its largest station with May planned to have nearly 50 percent more departures than the airline’s second largest city. This was Spirit’s one true hub in that it was able to connect people through Fort Lauderdale into Latin America.

Airlines had already been jockeying for position in Fort Lauderdale, as I wrote about last year when JetBlue made one of several moves to grow at the airport. For JetBlue, that had to be one of the big (only?) benefits of a Spirit merger. Yes, that was shot down by the government, but nobody in government is going to challenge JetBlue if it tries to take over the gates now.
For JetBlue this is a life or death move. It will never be the most important airline in New York, and its previous management team made the huge mistake of giving up the crown in Boston. JetBlue has rebuilt there, but it is not going to beat Delta at this point. That means Fort Lauderdale is its one true chance to have a dominant position at a valuable hub. The current management team is not going to squander this opportunity.
Since late 2024, JetBlue has been adding service like crazy, putting new dots on the map from FLL to:
- New: Dallas/Fort Worth, Guatemala City, Islip, Liberia, Manchester (NH), Norfolk, Orlando, San Pedro Sula, Tampa
- Returned: Aruba, Atlanta, Austin, Cartagena, Cleveland, Grand Cayman, Guayaquil, Jacksonville, New Orleans, Philadelphia, Phoenix, Pittsburgh, Santiago (DR), St Maarten, Syracuse
But now that Spirit is gone, JetBlue didn’t wait one second to put even more service into the market, announcing 22 new daily flights to new destinations:
- From Jul 9: Baltimore (3x daily), Charlotte (3x daily), Chicago/O’Hare (2x daily), Detroit (2x daily), Houston/IAH (3x daily), Nashville (3x daily), Ponce (1x daily)
- From Oct 1: Baranquilla (1x daily)
- From Oct 15: Cali (1x daily)
- From Nov 2: Columbus OH (1x daily), Indianapolis (1x daily)
As if that’s not enough, it is also adding frequencies on existing routes to Aguadilla, Austin, Dallas/Fort Worth, Raleigh/Durham, Santiago (DR), and Santo Domingo.
The goal has to be for JetBlue to take over Spirit’s entire FLL operation. Including the 5 new gates being built in a new Terminal 5 that are earmarked for JetBlue already, this would give JetBlue a dominant presence covering the southern half of the airport:

By my count last year, JetBlue had 15 gates with 5 more coming online in the new Terminal 5. And Spirit had 12 gates. Put those together and you have a powerhouse. Of course, JetBlue isn’t the only one that might want these gates, so who are the competitors?
- Allegiant has grown its Fort Lauderdale base to have more than 30 destinations in summer. The thing is… it still only has 15 daily flights using two gates regularly (a little more if you include Sun Country). It has grown and would like to grow more, but I can’t imagine it having designs on more than a gate or two. If Allegiant is smart, it’ll focus its efforts on trying to replicate the Sun Country model in Detroit now that it is the proud owner of that airline.
- Breeze didn’t even enter FLL until Nov of 2025, but it has grown there quickly, now operating to 14 destinations as of the coming summer schedule. It still only has 8 daily departures. It will grow more, but how much can it justify dedicating to this airport alone?
- Frontier has been interested in anything Spirit has done, dreaming of this day when it would be the lone big ULCC flying. But even with its growth, it only has 12 destinations from FLL and 8x daily flights. Frontier will have interest here, but if I were Frontier, I’d be looking more at taking over Spirit’s ops in Orlando as well as New York and smaller markets like DFW and Chicago. That’s the better play.
- United has long dreamed of a Latin hub in South Florida. It has no hub in the Southeast at all, having to rely on Houston as its best opportunity to connect into the region. Spirit’s 12 gates are not enough for a hub, but let’s not forget the Blue Sky partnership with JetBlue. It could be interested in acquiring more real estate in preparation for an eventual ability to take over JetBlue’s position in a merger. That’s all speculation, but it is something that has undoubtedly been pondered.
So how does this all play out? That lies at the feet of the Broward County Aviation Department which runs the airport. It has some very valuable and desirable real estate right now, and it has to figure out how to divvy it up. We can speculate about what makes the most sense, but in the end, the airport is going to certainly try to accommodate all the airlines that want to grow. JetBlue is first out of the gate, and maybe that will deter others from making a big move. After all, nobody has more to lose than JetBlue here.
