Allegiant Pet Policy
When transporting a pet by a commercial airline, it is extremely important to understand their pet policy. These policies vary between airlines. Some allow small pets to fly in the cabin and others don’t. It is important to know the answers to all your questions before making your decision to fly your pet on any commercial airline. Does Allegiant allow pets on my specific route? How much does it cost to fly a dog or cat on Allegiant? What documents will I need? What are the carrier requirements for Allegiant? All your answers related to Allegiant pet policy are answered below.
Note: It is important to mention that the pet policy of the airline that operates your pet’s route will preside over the policy of the airline that owns the route. This is important to note because if the operating airline changes during your trip, then you will likely need to claim and recheck your pet on the next airline. This will cause you to clear customs and enter the layover country. You will need time and extra documentation to accommodate this process during the layover unless flying domestically.
Classes of service offered to pets by commercial airlines
- In-Cabin: Pets traveling in the cabin must fly with an adult passenger and travel in an airline compliant
carrier stowed under the seat. - Checked Baggage: Pets traveling with a passenger that are not permitted in the cabin due to size or breed can be transported as checked baggage in the cargo hold.
- Air Cargo: Unaccompanied, very large pets or pets flying to countries that require that pets enter under air cargo will travel as manifest cargo in the hold.

Allegiant Pet Policy – In Cabin

Pets allowed flown by Allegiant in the cabin
Dogs and cats only are flown on Allegiant flights accompanied by passengers 15 years of age or older. Pets must be clean, healthy, harmless and mannerly.

We can arrange flights from anywhere in the world to anywhere you need to go on your time schedule, without the crowds or commotion of a commercial airport.

Allegiant does not ban any dog or cat breeds; however, owners of brachycephalic (snub-nosed) breeds should fly with a carrier that provides plenty of ventilation. Ask for a glass of ice during the flight to hydrate your pet.
