Allegiant Air Is Adding 27 New Routes to Florida This Summer — See the Full List

Allegiant Air is rolling out 27 new Florida routes for summer 2026 — including 13 first-ever nonstop markets — as the ultra-low-cost carrier seizes ground left open by Spirit Airlines’ collapse.

Allegiant Air moved to fill the vacuum left by Spirit Airlines’ collapse, launching 27 new nonstop routes to Florida for the June-through-September travel season — including 13 city pairs that have never had nonstop air service to the state from any carrier.

The expansion, which covers Allegiant’s June-through-September schedule, comes as the Las Vegas-based carrier capitalizes on the collapse of Spirit Airlines, a rival that ceased operations earlier this year and left a string of Florida routes unserved.

Allegiant has climbed to become Florida’s sixth-largest domestic carrier, moving up one spot from a year earlier because of Spirit’s exit, and now accounts for almost 7% of all Florida-U.S. flights. Despite that shift, the Las Vegas-based airline’s actual share of Florida flying held essentially flat, as rivals Breeze Airways, Frontier Airlines, and JetBlue also rushed to fill the void Spirit left behind, growing their own Florida schedules by 44%, 40%, and 32%, respectively, over the same period.

The new routes push Allegiant’s total Florida network to 282 routes for the summer — 280 connecting Florida with other states and two flying within Florida. Allegiant will serve 12 Florida airports during the season and plans 26,060 Florida flights between June and September, down slightly from 26,200 a year earlier, a decline of about half a percentage point.

Florida will account for 61% of Allegiant’s total flights this summer, with a median of 224 daily round-trip flights touching the state. Scheduling varies sharply by day, from a high of 343 flights on some Fridays to as few as 14 on certain Tuesdays. Allegiant’s older aircraft do not need to fly as intensively as newer planes, letting the carrier concentrate service on higher-demand days without discounting fares further to fill seats.

The 27 new routes span 25 airports and add 28,259 miles of network distance. Of the total, 11 launched in 2025 and 16 began service between January and June 2026. Three routes operated until April or May 2025, paused, and returned that October or November, meaning they did not fly between June and September 2025 but will this year.

Thirteen of the 27 routes — nearly half — are markets that have never had nonstop air service to Florida from any airline. Eight others were previously in Allegiant’s own network, last flown between 2008 and 2024. The remaining six fill gaps left by other carriers, including United Airlines’ former Denver-to-Destin-Fort Walton Beach service, discontinued in 2022, and Spirit’s former Fort Lauderdale-to-Atlantic City route.

Columbia, Missouri, and La Crosse, Wisconsin, are entering Allegiant’s network for the first time, while the carrier returned to Huntsville, Alabama, in 2025, a market it had not served since 2008. Allegiant also returned to Trenton-Mercer Airport in New Jersey with three Florida routes — to Fort Lauderdale, Punta Gorda and St. Pete-Clearwater — filling a gap left when Frontier Airlines stopped flying between Trenton and Fort Lauderdale in 2024. Introductory fares from Trenton start at $49 one-way.

“We’re excited to announce these new routes and believe it is an important time for Allegiant to increase travel options in these markets,” said Drew Wells, Allegiant’s chief commercial officer.

“Our mission is to offer service where it is needed most, and these additions ensure that affordable fares can remain available to consumers despite industry changes,” Wells said.

Among other new service: La Crosse to Orlando Sanford International Airport began May 21, 2026, with fares from $69 one-way. Columbia, Missouri, to Orlando Sanford began June 3, 2026, and Columbia to Destin-Fort Walton Beach began June 5, 2026, both from $59.

The Florida push comes amid strong financial results for Allegiant. The carrier reported record first-quarter 2026 revenue of $732.4 million, up 9.6% from a year earlier, with adjusted diluted earnings per share of $3.77, up 78.7%, and an adjusted airline-only operating margin of 14.9% — its best first-quarter performance since before the COVID-19 pandemic.

“We had a great start to the year, delivering another quarter of strong operational and financial results,” Anderson said in the company’s first-quarter earnings release.

“First-quarter demand was exceptional, particularly during peak periods, driving more than a 16 percent year-over-year increase in TRASM, with total yields up over 20 percent year-over-year. That performance allowed us to set an all-time quarterly record despite a 5.9 percent year-over-year reduction in capacity,” Anderson said.

“Our airline business was profitable. We were at about 7% margin. We led the industry in the fourth quarter [of 2025] in the US and in the first quarter of this year [2026] with nearly a 15% margin,” Anderson said in a June 12 interview with AeroTime Hub.

Allegiant also completed its acquisition of Sun Country Airlines on May 13, 2026, creating what the company called the leading leisure-focused airline in the United States, with a combined fleet of 195 aircraft serving nearly 175 cities, with approximately $140 million in annual synergies expected within three years.

“Today marks a defining moment in Allegiant’s history as we officially join forces with Sun Country to create the leading leisure-focused airline in the United States,” Anderson said.

The route additions come alongside a broader reshuffling of Allegiant’s network. The carrier reduced its systemwide schedule by 61 routes for summer 2026 compared to a year earlier, according to industry analysts, as it repositioned capacity toward higher-potential markets.

Outside Florida, 78 airports offer Allegiant service into the state this summer. Cincinnati generates the most departures, followed by Asheville, Knoxville, Allentown and Belleville, which serves the greater St. Louis area.

Allegiant has also announced eight additional Florida routes set to begin in the fourth quarter of 2026, including new Fort Lauderdale flights to Boston, Omaha, Pittsburgh and Kansas City and a new St. Pete-Clearwater-to-Philadelphia route.

As of the first quarter, Allegiant operated 123 aircraft, including 71 Airbus A320s in a 180-seat configuration, seven in a 177-seat variant, 28 Airbus A319s and 17 Boeing 737 MAX 8-200s, the model the airline is transitioning toward as its primary aircraft type.
