What documents does my pet need to fly internationally from the US?

Most countries require a veterinary health certificate issued within 10 days of travel, a USDA endorsement of that certificate, proof of rabies vaccination, and an ISO microchip. Some destinations add requirements like rabies titer tests, import permits, or parasite treatments.

How much does it cost to fly with a dog or cat?

Airline cabin fees typically run $125 to $200 each way. Cargo transport ranges from $200 to $1,000+ depending on the airline and route. On top of that, expect $200 to $500 for vet visits, health certificates, and USDA endorsement fees.

How far in advance should I start preparing?

Start at least 4 weeks before travel for straightforward destinations like Canada or Mexico. Countries that require a rabies titer test — Japan, Australia, and most of the EU — need 3 to 6 months of lead time because of mandatory waiting periods after the blood test.

Can cats fly internationally the same way as dogs?

Yes. Cats follow the same general process: microchip, rabies vaccination, health certificate, and USDA endorsement. A few countries have cat-specific rules (the UK requires a tapeworm treatment, for instance), but the steps are largely identical.
