Allegiant Air is a U.S. low-cost leisure airline selling nonstop fares with bags, seats, and other extras priced separately.

A cheap headline fare can become a very different total once luggage and seat choices are added. Allegiant Air makes the most sense when its nonstop route fits your dates and the full checkout price stays below the alternatives.
The Las Vegas-based carrier mainly links small and midsize U.S. cities with vacation markets. Its schedule, airport choices, and add-on pricing differ from the large hub airlines, so comparing only the first fare shown can be misleading.
Allegiant Air And Its Parent Company
Allegiant Air is the scheduled passenger airline at the center of Allegiant Travel Company, a Las Vegas-based company traded on Nasdaq under the symbol ALGT. The carrier has operated scheduled service since 1999 and uses the airline code G4.
Allegiant Air is not a large hub-and-spoke carrier built around frequent connections. Its main business is selling nonstop leisure trips between regional communities and vacation markets, often on routes that larger airlines do not serve nonstop.
How Does Allegiant Air Keep Fares Low?
Allegiant Air keeps base fares low by operating a leisure-focused, point-to-point network and charging separately for many optional services. The airline sells the flight first, then lets each passenger add bags, a chosen seat, priority access, and extra legroom.
Many routes avoid a connection at a major airline hub. Some also use smaller airports with lower operating costs or easier access for regional travelers. Service may run only on selected days, which helps Allegiant match capacity to vacation demand but gives passengers fewer backup choices when plans change.
Allegiant’s investor overview listed 576 routes, 128 cities, about 18 million annual passengers, and 123 aircraft in July 2026. Those figures move as routes open, pause, or return seasonally.
Allegiant Air’s Fare Structure And Add-Ons
An Allegiant Air base fare covers transportation and a seat assigned by the system if the passenger does not pay to choose one. A personal item is included, while overhead-bin bags, checked luggage, reserved seats, and several convenience products usually cost extra.
| Fare Element | Base Fare Status | What Travelers Get |
|---|---|---|
| Flight seat | Included | A seat is assigned at no charge during check-in if no seat was purchased. |
| Personal item | Included | One under-seat item up to 8 by 14 by 18 inches. |
| Carry-on bag | Paid add-on | One overhead-bin bag up to 10 by 16 by 22 inches. |
| Checked bag | Paid add-on | Up to four bags may be purchased; each standard bag can weigh up to 50 pounds. |
| Seat selection | Paid add-on | Passengers can choose a location before check-in instead of accepting the system assignment. |
| Extra legroom | Paid option | Allegiant Extra and Legroom+ are offered on selected flights. |
| Priority Access | Paid add-on | Earlier boarding can be purchased separately or included in some bundles. |
| Service bundle | Optional package | A bundle can combine common add-ons, but bundle terms and refund rules need checking before payment. |
Bag prices vary by route, travel date, and when the bag is added. Buying luggage during the original reservation is normally cheaper than waiting until the airport, so the fare comparison is the final total for every traveler in the party.
Where The Airline Flies And How Often
Allegiant Air concentrates on nonstop leisure routes rather than a dense daily business schedule. Las Vegas, Orlando, the Gulf Coast, Phoenix, and Florida beach markets are common network anchors, while many smaller departure cities receive limited weekly service. The official Allegiant company profile describes the carrier’s low-cost, nonstop focus.
Route frequency matters as much as fare. A route operating two or three days a week may not support a flexible return date or an easy same-day replacement, even when the nonstop schedule is convenient on the planned travel days.
Schedule check: Confirm both directions before reserving lodging or event tickets. A low outbound fare is not useful when the return flight runs on the wrong day.
What Travelers Should Expect At The Airport
An Allegiant Air trip works smoothly when check-in, bags, identification, and boarding are handled before the deadlines. Online and app check-in opens 24 hours before departure and closes 45 minutes before departure.
- Arrive at the airport about two hours before the scheduled departure.
- Reach the boarding-gate area at least one hour before departure.
- Drop checked bags within the airport’s accepted window; Allegiant advises doing this at least one hour before departure.
- Use the mobile boarding pass or print one before arriving when possible.
- Measure personal items and carry-ons with wheels and handles included.
- Reserve seats in advance when sitting together matters, since free assignments may separate a party.
Some smaller airports use outdoor ramps rather than enclosed jet bridges. Passengers needing mobility help can request assistance through the reservation, and required assistive devices are transported without a bag fee.
The Sun Country Acquisition Explained
Allegiant Travel Company completed its acquisition of Sun Country Airlines on May 13, 2026, but the two airline operations did not instantly become one booking system. Customers were told to manage existing trips with the airline shown on their reservation.
Allegiant and Sun Country continue operating separately while integration work proceeds and the carriers seek a single Federal Aviation Administration operating certificate. The parent company uses the Allegiant name, while current schedules, airport service, and customer support still depend on which airline sold the ticket.
Compare The Full Flight Price
Allegiant fares should be compared after adding every item the trip requires, not against another airline’s base price alone. A nonstop itinerary may still save money and several hours, especially from a regional airport, but a bag-heavy family can see the gap narrow quickly.

Who Allegiant Fits Best
Allegiant Air suits leisure travelers with fixed dates, light luggage, and access to one of its nonstop routes. The airline is less convenient for trips needing daily frequency, easy rebooking, a large connecting network, or several included services.
- Strong fit: A couple carrying personal items on a nonstop weekend trip.
- Strong fit: A traveler who saves a long drive by using a nearby regional airport.
- Mixed fit: A family paying for multiple bags and adjacent seats.
- Weak fit: A time-sensitive traveler who needs several flights each day as backups.
- Weak fit: A passenger connecting onward on a separate ticket with little recovery time.
A Simple Booking Decision
An Allegiant booking is a strong choice when the route is nonstop, the schedule matches both travel dates, and the all-in total beats a comparable itinerary. The lowest displayed fare by itself is not enough evidence.
- Price the fare for every passenger.
- Add the exact number of carry-on and checked bags.
- Add reserved seats when the party must sit together.
- Compare the departure airport’s parking, drive time, and ground transport.
- Check the next available flight in case the original service is disrupted.
- Read the change, cancellation, and bundle terms before paying.
Choose Allegiant when its nonstop convenience survives that six-step comparison. Choose another airline when schedule flexibility, connections, or included baggage matters more than the low starting fare.
