What to Expect When You Fly With Allegiant Air

A low-cost airline is not the same experience as flying with a legacy flight company, such as Delta or United. The main target is efficiency. Expect a clean and professional cabin environment, though premium amenities like free meals are not included to keep fares low. and seat-back screens. The majority of the  Allegiant Air flight booking services will have you seated in a regular leather seat with a seat pitch (legroom) of about 30 to 34 inches.

The boarding process is generally organized into zones. When you have bought priority boarding or the Allways Rewards Visa card, then you will be one of the first boarded. Since Allegiant frequently lands at small, secondary airports (such as Orlando Sanford rather than Orlando International), the terminals might be less full and easier to get around, but could be further away.

Frequent Flyer Program:

Unlike traditional programs that rely on "miles flown," Allegiant’s Allways Rewards is a spend-based loyalty program. It is incredibly easy: you get a certain number of points due to the amount of money that you spend on the Allegiant site.

  • Earning: Members receive 1 point for every one dollar. On itineraries above 500, you will gain 2 points for every dollar.
  • Redeeming: Points are worth 1 cent each. No blackout dates and maximum redemption requirements. Once you accumulate 500 points ($5 value), you can redeem them for your next booking, then use them to take away 5 dollars on your next flight.
  • The Visa Card: The Allways Rewards Visa card is the card of choice of frequent fliers, with 3x points earned on Allegiant purchases, plus such benefits as a free beverage onboard and priority boarding.

Flexible Booking and Cancellations for Allegiant Air Flights

Flexibility is a key concern for modern travelers. Allegiant offers a "Trip Flex" add-on during the initial Allegiant Air flights purchase. In the absence of Trip Flex, the cost of making changes or cancellations, on a per-segment basis, is normally quite high, and no changes are made 7 days before a flight.

But when you buy Trip Flex, you can amend your flight or cancel it and get a voucher one time with no charge to pay the normal change fees, unless the change is made at least one hour prior to departure. This offers hope to those whose arrangements may be changed at the nick of time. Allegiant's Trip Flex offers great peace of mind. For more on how this compares to industry standards, see our cancellation policy guide.

Allegiant Air Highlights

Allegiant keeps things simple by offering a:

Single Cabin Class: Economy. 

Note: You won't find Business or First Class sections on their planes. Instead, the airline offers "Legroom+" seats and "Giant Seats" on certain aircraft (primarily the newer Boeing 737 MAX fleet). These are extra-pitch or extra-width seats, which have the same level of service as all of the cabin. In  Allegiant air plane ticket search, it is important to keep in mind that all people are already in the same "class," but what is offered to you depends on your bundle.

Allegiant has been modernizing its fleet to become fuel efficient and reliable. Replacement of older MD-80s by all Airbus was a significant milestone, and the introduction of Boeing 737 MAX aircraft in the recent past has increased their capacity even more.

The addition of the Boeing 737 MAX aligns Allegiant with major carriers like United Airlines, which also utilize this efficient aircraft.

Understanding the baggage policy is crucial to avoiding "sticker shock" at the airport. Allegiant is very strict with dimensions, as their business model depends on these ancillary fees.

For Domestic Flights:

  • Personal Item: FREE (must fit under the seat; max 7 x 15 x 16 inches).
  • Carry-on Bag: Fee applies. Must fit in the overhead bin (max 9 x 14 x 22 inches).
  • Checked Bag: Fee applies. Max weight 50 lbs; max size 80 linear inches. Pre-paying during your Allegiant Air flight booking is significantly cheaper than paying at the airport counter.

For International Flights:

Allegiant is mostly a domestic airline, although on occasion, they serve some international leisure destinations in the area (such as the Caribbean). The luggage policy has not changed much; it is what you pay. Never rely on domestic limits on weights on international travel because domestic rules sometimes have different limits on the weight of things to be carried.

Budget airlines are strict with bag sizes. Unlike full-service carriers where policies might be more lenient during an American Airlines flight change, Allegiant fees are segment-based.

Food

Allegiant does not provide free snacks or water. However, they have an extensive "Buy on Board" menu. You can buy snack boxes (such as Horizon or Getaway boxes), including crackers, cheese, meat, and sweets. It is also able to offer a large selection of alcoholic drinks, such as fine liquors and wines.
