Key takeaways
Cabin, checked, and cargo travel
Small eligible pets may be accepted in an under-seat carrier on some flights. Other animals may need an airline cargo service, while certain routes or aircraft may not accept animals at all. Temperature restrictions, breed limitations, connection rules, and seasonal embargoes can apply.
- Ask whether the pet counts as a carry-on item
- Confirm maximum combined pet-and-carrier weight
- Check every operating carrier on a multi-airline itinerary
Documents and destination rules
Domestic and international trips can require health certificates, vaccination records, microchip details, import permits, or quarantine arrangements. Requirements may be based on arrival country, transit country, and return journey—not only the outbound flight.
- Use official government and airline sources
- Check document issue and validity windows
- Carry paper and digital copies where accepted
Preparing for the airport
Introduce the carrier before travel, label it securely, and arrive with extra time. Ask a veterinarian about feeding and medication rather than making last-minute changes. Security screening procedures may require the animal to leave the carrier temporarily.
Frequently asked questions
Can I add a pet after booking?+

Are pet fees included in the displayed airfare?+
Usually not. Pet transport is commonly charged separately by the airline and may be payable at booking, by phone, or at the airport.
Do emotional support animals follow service-animal rules?+
Policies differ by jurisdiction and airline. Many carriers treat emotional support animals as pets; verify the current operating-airline policy.
Can a pet travel on a connecting itinerary?+
Possibly, but connection airports, aircraft, partner airlines, and border rules can create additional restrictions.
