Most US airlines require two core documents for any pet traveling in cabin or as checked baggage: a health certificate issued by a licensed veterinarian within 10 days of travel, and a current rabies vaccination certificate. For international flights, a USDA APHIS-endorsed health certificate is typically required in addition to or instead of a standard vet-issued certificate.
- Most airlines require a veterinarian-issued health certificate dated within 10 days of the flight — not the rabies certificate, a separate document your vet completes at a pre-travel appointment.
- A current rabies vaccination record is required separately by most US airlines and virtually all international destinations.
- Breed restrictions are real and enforced: many airlines ban brachycephalic (short-nosed) breeds in cargo and some in cabin — check before you book, not at the gate.
What does an airline health certificate actually require?
A health certificate for airline travel — also called a Certificate of Veterinary Inspection (CVI) — is a document completed by a licensed veterinarian stating that your pet has been examined and appears healthy enough to travel. Key elements it includes:
- Pet identification: Species, breed, color, age, sex, and any identifying markings or microchip number.
- Owner information: Name and contact details.
- Examination findings: Confirmation that the pet was examined and found free of infectious or communicable disease.
- Vaccination status: Typically includes rabies vaccination date and certificate number, and sometimes other core vaccines depending on the airline's requirements.
- Veterinarian license number and signature.
The 10-day rule is enforced strictly by most airlines: the certificate date is the exam date, and most carriers will not accept certificates older than 10 calendar days from the date of travel. Schedule your vet appointment accordingly — within the 10-day window but with enough time to allow for any issues or corrections.
For international travel, the health certificate may need to be the USDA APHIS Form 7001, endorsed by both a USDA-accredited veterinarian and a USDA Veterinary Services office. See the pet passport records guide for international documentation details, and verify requirements at USDA APHIS Pet Travel (accessed September 23, 2026).
What is the difference between cabin and cargo for airline pet travel?
Airlines distinguish between three ways a pet can fly:
- In-cabin: The pet travels in a carrier under the seat in front of you. Most airlines limit in-cabin pets to small dogs and cats that fit in an airline-approved soft-sided carrier under the seat (typically 18"L × 11"W × 11"H or smaller). Weight limits including the carrier are usually 15–20 lbs total. A health certificate is required.
- Checked baggage (cabin-connected cargo): The pet travels in the cargo hold in a hard-sided crate but on the same aircraft as the owner. This option has been discontinued by many major US airlines following safety concerns, particularly for brachycephalic breeds. Check whether your airline still offers this before planning.
- Cargo (air freight): The pet ships as air cargo, often on a separate flight. Typically used for large dogs that can't fit in cabin. Documentation requirements are similar but the logistics — carrier size, airline-specific crate requirements, booking process — differ significantly.
Regardless of method, the health certificate and rabies certificate are required. For cargo, some airlines require the USDA-endorsed version even for domestic travel.
Which dog breeds are restricted by airlines?
Brachycephalic breeds — those with shortened snouts — are restricted by many airlines because they are at elevated risk of respiratory distress in pressurized or temperature-stressed conditions. Common restricted breeds include:
- English Bulldogs, French Bulldogs, American Bulldogs
- Boston Terriers, Pugs
- Boxers, Shih Tzus, Pekingese, Lhasa Apsos
- Persian cats, Himalayan cats, Burmese cats
Some airlines ban these breeds from cargo entirely; others restrict them in both cabin and cargo. Restrictions also vary by route, season, and temperature at origin and destination airports. This is not a standard list — each airline maintains its own. Check your specific airline's pet policy page before booking any ticket, not after.
How do domestic and international airline requirements differ?
For domestic US flights, a standard vet-issued health certificate (within 10 days) and a current rabies certificate cover most airline requirements. Some airlines have additional restrictions on destinations (Hawaii requires a quarantine protocol regardless of how the pet arrives).
For international flights, requirements layer significantly:
- The health certificate is typically a USDA APHIS-endorsed form, not just a standard vet certificate.
- The destination country's import requirements apply — these may include microchip verification, rabies titer tests, specific waiting periods, or advance import permits.
- Some countries require the health certificate to be translated or accompanied by a country-specific form in addition to the APHIS form.
- The airline itself may have additional international requirements on top of the destination country's rules.
Always verify requirements from both the airline and the destination country's official animal import authority. USDA APHIS Pet Travel maintains destination-specific guides that are the most reliable US government source for international requirements.
How does Voocie help with airline pet documentation?
When your vet completes a health certificate or adds vaccines to your pet's record, they CC the pet's private Voocie address. The document and vaccination data are automatically added to your pet's health record. At the airport, you can pull up a shareable link that shows the complete vaccination history and any uploaded certificates — no digging through a folder, no wondering if you grabbed the right piece of paper.
If an airline agent needs to verify your pet's rabies certificate or review vaccination dates, you hand them your phone with the sharing link open. The record is organized, dated, and complete. Voocie costs $99/year, or about $10/month. Start at voocie.com/start.
Frequently asked questions
Do I need a health certificate for my dog on a domestic flight?
Yes, most US airlines require a health certificate issued within 10 days of travel for any pet, regardless of whether the flight is domestic or international. Some airlines accept a rabies certificate alone for in-cabin pets on certain domestic routes, but a full health certificate is the safest assumption. Check your specific airline's pet policy before your appointment.
Can I get a health certificate at the airport before my flight?
No. A health certificate must be issued by a licensed veterinarian after a physical examination. Some airports have veterinary services nearby, but scheduling a same-day appointment and traveling immediately creates significant timing risk. Schedule the exam within the 10-day window before your flight date.
What if my health certificate is 11 days old when I reach the airport?
Most airlines will refuse boarding for your pet. The 10-day rule is enforced from the certificate date. If you miss the window, you'll need a new exam and a new certificate. There is typically no grace period.
Does my cat need the same documents as my dog for a flight?
Yes — most airlines apply the same health certificate and rabies certificate requirements to cats. The only material differences involve species-specific breed restrictions (brachycephalic cat breeds have cargo restrictions similar to brachycephalic dog breeds).
What should I bring to my pre-flight vet appointment?
Bring your pet's full vaccination history (or share your pet's Voocie record with the vet beforehand), your flight itinerary including the destination, and the airline's specific pet policy page if you have it. The vet needs the destination to issue the correct form, and the airline's requirements vary enough that showing them the policy helps ensure the certificate meets the exact format expected.
