How to book a pet on Spirit Airlines
Almost every airline requires you to add a pet to your reservation by phone — there is no online self-service for in-cabin or cargo pets at the major carriers, because the airline must confirm there is space on the specific aircraft type and route. Call 1-855-728-3555 within 24 hours of buying your ticket and ask the agent to add the pet to your booking. You will be quoted the fee at the time of booking and pay it at airport check-in. Bring printed proof of vaccinations and a recent veterinary health certificate, especially for international itineraries.
At the airport, plan to arrive 90 minutes before a domestic departure or three hours before an international departure. The airline gate agent will inspect your carrier, attach an in-cabin pet tag, and confirm that your pet meets the under-seat dimension and weight limits. If your animal is travelling in cargo, you will drop them off at the carrier's dedicated cargo-acceptance facility (separate from the passenger terminal) at least four hours before departure for kennel inspection and loading.
