If you fly Allegiant between the Midwest and Florida, check your options before booking for 2027. The Las Vegas-based budget carrier has scrapped 20 nonstop routes into seven Florida airports, and based on its current booking window, none are due back before mid-May 2027.

Destin–Fort Walton Beach takes the biggest hit, losing seven routes — Asheville, Clarksburg, Evansville, Huntington, Las Vegas, Lexington and Shreveport. Fort Lauderdale loses four, Orlando Sanford three, and there are single cuts at Jacksonville (Des Moines and Nashville), Punta Gorda (New Orleans), Sarasota (Nashville) and St. Pete–Clearwater (Little Rock and Tulsa).

Here's the twist: US Department of Transportation data shows these weren't failing routes. Twelve of the 20 were flying at least 80% full in 2026, and three topped 90%. Orlando Sanford–Austin ran at 93.4%, St. Pete–Clearwater–Little Rock at 91.4% — an improvement of more than 18 points year over year — and even Destin–Las Vegas was 90% full. Sixteen of the 18 routes with comparable 2025 figures actually improved. Only four flew less than half full.

So why cut them? Because a full plane isn't always a profitable one, and because Allegiant has found a hotter market. Fort Lauderdale is the story: the airline is growing flights there by 33% in the second half of this year, adding nine new routes including Boston, Albany, Rochester, Chicago Rockford and Chattanooga, on top of its existing 34 destinations. The gap in the market appeared after Spirit Airlines' collapse at its former South Florida stronghold, and Allegiant is racing JetBlue and Breeze Airways to fill it. JetBlue is now Fort Lauderdale's biggest carrier; Breeze has added 14 routes there since joining in November.

The math backs the strategy. Allegiant cut overall capacity by 6.8% in the second quarter yet pushed revenue per available seat mile up 24.6%. Elsewhere in its network it's pulling back hard — Las Vegas flights are down 9% in the second half, and the airline has exited Los Angeles, Oakland and San Diego entirely.

For travellers, the practical impact depends on where you live. Smaller Midwest and Appalachian cities — Evansville, Huntington, Clarksburg, Shreveport — lose their direct link to Florida's Emerald Coast, so expect connections or drives to alternative airports. Meanwhile anyone with South Florida plans gets more options than ever, as Allegiant joins JetBlue and Breeze in piling capacity into Fort Lauderdale.

Even Orlando Sanford–Austin, a 93% full route linking Texas to Florida, is gone for now — proof that load factors alone don't keep routes alive when an airline is redeploying planes to where the money is. There's a slim chance some of these routes return as shortened seasonal services next year, but the booking system currently says otherwise. If a direct flight from your hometown to Destin, Fort Lauderdale or Sanford was part of your plan, it's worth booking alternatives early.
