Things To Know Before You Fly Allegiant Air

Allegiant Air is among the low-cost airline carriers in the United States that mainly caters to 128 destinations within the United States only. Its fleet of a little over 100 Airbus aircraft does offer a good experience to passengers. It is known as a leisure class of airline, which means it is not the type of airline you would expect there to be a First Class or Business Class section. Combined with their ultra-low-cost fares, they are a number one choice for many flyers who are looking to get to that once a year holiday spot safely and economically.

In this travel guide prepared by Treknova, we will take a look at a few things you should know before flying on Allegiant Air flight.

Know Before You Fly Allegiant Air

Here are a few important things that will help travellers know a little more about Allegiant Air, what to do and what to avoid.

Allegiant Air’s Destinations and Flight Schedule

Allegiant Air is a budget airline that primarily operates to and from regional airports in the United States. However, that does not mean they do not cater to top destinations. Currently, Allegiant airline serves more than 450 routes to more than 150 cities in the United States, including Charleston, South Carolina; Fort Walton Beach, Florida and San Juan, Puerto Rico. Also remember that they do offer a number of seasonal routes.

Allegiant’s flight schedule is a little different for the reason that the airline may not have a daily flight to your preferred route. Which means now you may not be able to fly in and out on the days you want. Because of their limited flight schedule and the fact that the hot destinations fill up very quickly, the best strategy is to book as early as you can.

On the other hand, a route that is not serviced every day is just one way the airline is able to give you low fares. Know more about Allegiant Airlines cancellation and other policies from our website.

Allegiant offers Budget Flights at Cheap Deals

A main reason that Allegiant flights are cheap is, like other low-cost airlines, the airline carrier charges fees for a number of things that other major airlines give you for free. Although their base fares look cheap, but you also have to account for additional fees when you bundle your trip or pay for extras.

Below are items for which you might be required to pay fees on an Allegiant flight:

  • Seat selection
  • Carry-on bag
  • Checked baggage
  • TripFlex (allows you to avoid change fees)

Another big expense to consider with Allegiant is their baggage fees.

Allegiant’s Baggage Fees

Allegiant charges fees of up to $35 per bag each way for the first and second checked bag with the specific amount dependent on the airports you depart and arrive at. Every passenger is allowed to bring two items on-board, which include a personal item and one carry-on bag.

Allegiant’s baggage policy details have been shared below:

(a) Personal Item: This includes your personal items (such as a purse, briefcase, laptop, etc.) that are free, as long as the item(s) can be stored completely under the seat in front of you.

The maximum size for a personal item is 7 inches x 15 inches x 16 inches (17.8 cm x 38.1 cm x 40.6 cm).

(b) Carry-On Bag: The maximum size allowed on-board for carry-on bag is 9 inches x 14 inches x 22 inches (22.9 cm x 35.6 cm x 55.9 cm).

(c) Checked Baggage: The maximum size allowed on-board for checked bag is 80 linear inches (203.2 cm) in height + width + depth.

As with other airlines, they do put an additional charge for overweight and/or excess bags.

Mobile Boarding Passes

There is online check-in available from 24 hours up to 45 minutes before your flight’s scheduled departure. You can also download and print out your boarding pass through the main page of the website or use the Allegiant Air mobile app.

Priority Boarding

Allegiant Air offers the vital option of Priority Access upgrade which gives all the passengers the opportunity to board the plane before other passengers. Its cost is between $4 and $12.

Flying with Children

If you are flying with a child who is older than two years, you are required to purchase separate seat. Also, such minors must be accompanied by a fare paying customer aged over 15 years. There are two booking options that are available for children:

  • Either as a ticketed passenger seated in an FAA-approved car seat
  • As a lap child on the seat of an adult on the same reservation

You will need to show proof of age for lap children though. Passengers under 18 years may use other documentation, which can include their date of birth. This can be in the form of a birth certificate. Passengers without any sort of government-issued identification should have to undergo additional security screening. Each fare-paying passenger travelling with a child may travel with a diaper bag at no charge. The diaper bag will not count as your personal item or carry-on baggage.

Seating for Infants and Children

Children weighing under 40 pounds (18 kg) should be secured in an FAA-approved car seat or harness-type device when travelling on Allegiant Air flight. The approved car seat style child restraint systems will have one or more of the following labels:

  • The FMVSS.213 insignia.
  • This is indicating that they are certified or have been approved for use in motor vehicles and on aircraft.
  • Language indicating they provide confirmation to all the applicable federal motor vehicle safety standards.

Any car seat wider than 17.88 inches is most unlikely to fit in an Allegiant airplane seat. The only harness-type device will be approved by the FAA is at the AmSafe Aviation CARES. It is designed for children weighing between 22 and 44 pounds (20 kg) and must include a label that says, “FAA Approved in Accordance with 14CFR 21.305(d), will be Approved for Aircraft Use Only.”

Unaccompanied Children

Allegiant Air does not offer unaccompanied minor services. This means children that are fourteen years old and younger must be accompanied by an adult that is at least 15 years or older. Children that are between the age of fifteen and seventeen years old can be booked online with no extra fee.

Flying Being Pregnant

Allegiant airlines require a note from a physician for all the clearing expectant mothers to fly if their due date is within forty-five days or less of travel. Other than that, there are no restrictions of any kind.

Group Bookings

You may book up to nine passengers on a single itinerary, while multiple reservations are required to accommodate more travellers. There is also this option in Allegiant Air Charter, which allows for very large groups to fly to destinations not on the normal flight routes. This service is more expensive than buying standard scheduled service tickets, but believe me this is totally worth every penny.

Accessibility and Medical Equipment for Passengers with Disability

You can also complete the entire Customer Request For Assistance Form or simply contact the Allegiant Reservations Center on 1-702-505-8888 to request any sort of additional services, such as the wheelchair assistance, seating accommodation, stowage of an assistive device / escort assistance for a visually impaired passenger is also available.

Pets and Service Animals

Allegiant airlines allows passengers to bring in animals/pets in the passenger cabin of the aircraft on flights within the continuous flight of 48 United States and San Juan, Puerto Rico. Note that only domestic cats and dogs are permitted in the flight, and they must be transported in a soft-sided leak-proof carrier that fits under the seat easily:

  • The carrier should be no larger than 9″ H x 16″ W x 19″ D.
  • No more than two pets are allowed per carrier.
  • Pets must be able to stand and turn inside the carrier.
  • Remember: A pet carrier is not included in the carry-on baggage limitations.

You may travel with a maximum of two pets per carrier in the main cabin. To book a reservation with a pet, click the “Add a Pet in Cabin” link on the Travellers section when booking your reservation online.

Allegiant does not require a health certificate for pets travelling in the cabin.

Giving 48-hour advance notice is also recommended. To add a service animal or emotional support animal, select the Travel with Pets option below the passenger name input section.
