About Allegiant Air
Allegiant Air (IATA: G4) is a US ultra-low-cost carrier (ULCC) built around a simple idea: connect smaller, underserved cities directly to popular vacation destinations, skipping the big-hub connections most travelers are used to. Rather than a traditional hub-and-spoke network, Allegiant runs a point-to-point leisure model, often flying just a few times a week on a given route to match seasonal vacation demand.
Allegiant keeps base fares low by unbundling almost everything — seats, carry-on and checked bags, and priority boarding are all optional extras purchased separately. Its largest base is Las Vegas Harry Reid International Airport (LAS), supplemented by numerous smaller focus-city bases such as Punta Gorda (PGD), St. Pete–Clearwater (PIE), and Orlando Sanford (SFB). FareOptic compares Allegiant fares so you can see the real all-in price before you book.

Allegiant Rewards & Savings
Allegiant does not run a traditional miles-earning frequent flyer program. Instead, it offers a co-branded credit card and a bundled savings package as its main loyalty tools.

No Mileage Program

Trip Flex
An optional add-on that allows one free date change per one-way trip, giving flexibility without paying a standard change fee.
Allegiant Air Baggage Policy
Allegiant's base fare includes only a small personal item. Carry-on and checked bags are paid add-ons priced by route, and cost less when purchased in advance rather than at the airport.

| Carry-on bag | Paid add-on, priced at booking |
| 1st checked bag | Paid add-on, priced at booking |
| 2nd checked bag | Paid add-on, higher fee |

Tips to Book Cheap Allegiant Air Flights
- 1.Compare the full checkout total, not just the headline fare — bags, seats, and priority boarding add up quickly on Allegiant.
- 2.Book early: Allegiant often flies only 1–3 times per week on leisure routes, so seats and low fares sell out fast on popular travel dates.
- 3.Add carry-on and checked bags during booking rather than at the airport — pre-purchased bag fees are meaningfully cheaper.
- 4.Consider the Allegiant Extra bundle if you need a bag, seat, and priority boarding — it is usually cheaper than buying each separately.
- 5.Fly out of a smaller Allegiant focus city like Punta Gorda (PGD) or St. Pete–Clearwater (PIE) to skip big-airport congestion on both ends.
- 6.Sign up for Allegiant's email deals — the airline runs frequent flash sales on its leisure routes.
- 7.Since flights are less frequent, always double-check the exact days of week a route operates before planning your trip dates.
- 8.Use FareOptic to compare Allegiant's all-in price against Spirit, Frontier, and Southwest for the same leisure routes.

Frequently Asked Questions
Everything you need to know about booking Allegiant Air flights on FareOptic
Does Allegiant Air have a frequent flyer miles program?
No. Allegiant does not operate a traditional miles-earning loyalty program. Instead, it offers the Allegiant World Mastercard co-branded credit card, which earns points redeemable for flights and the "Allegiant Extra" bundle, which packages a bag, seat, and priority boarding at a discount versus buying each separately.
Why are Allegiant fares so cheap and then more expensive at checkout?
Allegiant is an ultra-low-cost carrier (ULCC) that unbundles nearly everything. The advertised base fare covers only a seat and a personal item — carry-on bags, checked bags, seat selection, and priority boarding are all optional paid add-ons shown during checkout, which is why the final total is higher than the headline fare.
Which cities does Allegiant fly to?
Allegiant specializes in point-to-point leisure routes that connect smaller and secondary US cities directly to popular vacation destinations, bypassing large-hub connections. Its largest base is Las Vegas Harry Reid International (LAS), with additional focus-city bases including Punta Gorda (PGD), St. Pete–Clearwater (PIE), and Orlando Sanford (SFB).
How often does Allegiant fly its routes?
Unlike major network carriers, Allegiant typically operates lower frequency service on many routes — often just 1 to 3 flights per week — since its model targets leisure travelers rather than daily business commuters.
Can I cancel an Allegiant ticket for a full refund?
Yes. Like all US airlines, Allegiant must honor the federally mandated 24-hour risk-free cancellation rule: if you cancel within 24 hours of booking and the flight departs at least 7 days later, you get a full refund. After that window, Allegiant fares are generally non-refundable and subject to change fees.
What cabin class does Allegiant offer?
Allegiant flies an all-Economy cabin — there is no Business or Premium Economy class. Seating comfort and extras like legroom seats can be purchased separately as add-ons.
