Allegiant Air has built a reputation as the airline that connects smaller cities across the United States to the country’s most popular vacation destinations. With an ultra-low-cost model, a no-frills philosophy, and an expanding fleet, Allegiant serves millions of travelers annually who prioritize affordability and simplicity when booking their leisure trips.
History
Allegiant Air was founded in 1997 and began operations in 1999, initially headquartered in Fresno, California. Its first commercial flight connected Fresno with Las Vegas. In 2001, the airline relocated its headquarters to Las Vegas, Nevada, a move that better aligned with its focus on leisure travelers and proximity to major tourist traffic.
Allegiant’s business model quickly evolved into one focused on underserved routes, offering nonstop service from small and mid-sized cities to popular vacation spots like Las Vegas, Orlando, and Phoenix. By avoiding major airline hubs, Allegiant carved out a unique space in the U.S. aviation market.
Over the years, Allegiant expanded its network and grew its fleet, earning a reputation for low fares, simplified service, and operating in markets largely ignored by larger carriers.
Fleet and Aircraft
As of 2025, Allegiant Air operates a fleet of 130 aircraft, consisting mainly of Airbus narrow-body jets:
- Airbus A319-100 – 35 aircraft
- Airbus A320-200 – 94 aircraft
- Boeing 737 MAX 8-200 – 1 aircraft currently in service, with more on order
Allegiant has made substantial investments in modernizing its fleet. In 2022, the airline placed an order for up to 100 Boeing 737 MAX aircraft, marking a major shift in its fleet strategy as it moves toward more fuel-efficient and reliable aircraft.
This move is expected to significantly reduce operating costs, improve environmental performance, and allow Allegiant to increase its range and route flexibility over the next decade.
Hubs and Focus Cities
Allegiant does not operate traditional hubs in the way legacy airlines do. Instead, it uses a system of focus cities that function as mini-bases for scheduling and maintenance operations. These include:
- Las Vegas, Nevada (LAS) – Allegiant’s home base and operational center
- Orlando/Sanford, Florida (SFB)
- St. Petersburg/Clearwater, Florida (PIE)
- Punta Gorda, Florida (PGD)
- Phoenix/Mesa, Arizona (AZA)
- Nashville, Tennessee (BNA)
- Cincinnati, Ohio (CVG)
- Indianapolis, Indiana (IND)
- Los Angeles, California (LAX)
- Grand Rapids, Michigan (GRR)
These focus cities allow Allegiant to maintain high aircraft utilization while keeping operating costs low. Each base provides nonstop service to smaller communities throughout the U.S.
Destinations
Allegiant Air serves more than 120 destinations across the United States, with a clear focus on point-to-point leisure routes. These routes frequently connect second-tier cities—often without any other nonstop airline service—to popular vacation destinations.
Some of the most popular destinations in Allegiant’s network include:
- Las Vegas, NV
- Orlando, FL
- Phoenix, AZ
- Fort Lauderdale, FL
- Savannah, GA
- San Diego, CA
- Myrtle Beach, SC
- Charleston, SC
In 2025, Allegiant added 44 new nonstop routes to its schedule, including service to Columbia, South Carolina; Gulf Shores, Alabama; and more regional cities eager for affordable direct flights to warm-weather getaways.
Travel Experience
Allegiant offers a streamlined and à la carte travel experience designed to keep base fares low. Passengers pay only for the services they choose, such as:
- Seat selection
- Carry-on and checked baggage
- Priority boarding
- In-flight food and beverages
Seats on Allegiant flights are all economy class. While there is no seatback entertainment, travelers can access entertainment and information via their mobile devices. Flights do not offer Wi-Fi at this time, as part of the airline’s efforts to maintain operational simplicity.

Allegiant’s Future
Allegiant is aggressively pursuing fleet modernization and network expansion to maintain its growth trajectory in the ultra-low-cost segment. The airline’s Boeing 737 MAX order signals a major evolution for the company, allowing it to reach new destinations and improve operational performance.
Allegiant has also entered into a partnership with the yet-to-open Sunseeker Resort in Port Charlotte, Florida. This vertically integrated travel experience is part of a broader strategy to bundle flights with hotels, rental cars, and vacation packages, increasing value for leisure travelers and boosting ancillary revenue.
With demand for domestic leisure travel remaining strong, Allegiant is positioning itself to capture an even larger share of the U.S. vacation market. Its low-cost structure, underserved-city strategy, and focus on nonstop routes make it a popular choice for families, retirees, and weekend adventurers alike.
