Allegiant Air pet policy allows for in-cabin pet travel but does not offer a checked baggage or cargo option. Small cats and dogs are permitted in the cabin, but passengers with larger animals may need to seek alternative travel accommodations. Allegiant is popular among budget travelers looking for a quick weekend getaway.  

This small airline is designed for leisure travelers moving between small cities, offering limited passenger airline services at low costs. However, the airline can offer these low rates due to the large number of after-the-fact fees. You may accumulate extra expenses for something as simple as not printing your boarding pass at home, for example. You need to know the rules and restrictions for pet travel on any airline, and this includes Allegiant Air pet policies.  

Here’s what you need to know about Allegiant Air pet policy, no matter your departure or arrival airport.  

  • Flying with Pets in the Cabin: To fly in the cabin, your cat or dog must fit comfortably in the carrier, which must—in turn—slide comfortably under the seat in front of you. To make sure you can successfully fly with your pet, read about the Allegiant Air policies for pets in the cabin.  
  • Service Animal Policies: Service animals are welcome on all Allegiant Air flights. Emotional support animals no longer qualify as service animals per Allegiant Air travel policies. Though certain exemptions are provided to these animals, rules and restrictions may still apply. Learn about specific Allegiant Air service animal policies in Section 48 of the airline’s Contract of Carriage. To determine if your dog qualifies to be certified as a Psychiatric Service Dog and can be accepted as such on Allegiant Air, you can visit Pettable’s PSD service.


Other Allegiant Air Pet Policies and Programs 

Allegiant Air allows pets on flights within the contiguous 48 states, San Juan, and Puerto Rico. Though the cabin-only option can come as a relief to some pet owners, it may dissuade other travelers from utilizing the airline. Size and weight restrictions are placed on every animal traveling via plane. If your dog is too large to fit under the seat, Allegiant may not be the airline for you. Their flight rates may be low, but you should never risk needing to board Fido or Fluffy at the last minute.  

When traveling with Allegiant, you and you alone are responsible for taking care of your animal. This means that it is your responsibility to bring him to the nearest pet relief area as soon as you arrive at your destination.
