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. Can my pet fly in the cabin on Spirit Airlines? How much does it cost to fly a dog or cat on Spirit Airlines? What documents will I need? What are the carrier or crate requirements for Spirit Airlines? All your answers related to Spirit Airlines 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.
