United Airlines Pet Transport Policy

Cabin allowed Cargo suspended

United Airlines allows small pets in the passenger cabin but does not offer a general cargo pet service. The airline is based in Newark (EWR), San Francisco (SFO), Houston (IAH), Chicago (ORD).

CRITICAL: United does NOT offer cargo pet transport for regular customers. In-cabin only. This is a major limitation for large dogs or routes where cabin pets aren’t permitted.

Frequently Asked Questions

Yes, for small dogs. United Airlines allows pets in the cabin up to around 8kg including the carrier. The carrier must fit under the seat in front of you. Check the current weight and size limits when booking, as these change.

Contact the airline cargo desk directly, or use an IPATA-accredited pet transport agent. Book as early as possible. Space for live animals is limited, and airlines often have only a few slots per flight. Confirm the booking 48-72 hours before departure.

United Airlines imposes restrictions on brachycephalic (flat-faced) breeds. Policies vary by season and route. Always check the current policy for your specific route and travel dates. Some airlines allow flat-faced breeds with a vet certificate confirming fitness to fly.

At minimum: a valid veterinary health certificate (usually issued within 10 days of travel), proof of microchip (ISO 11784/11785 standard), and up-to-date vaccination records. Import-specific documents depend on the destination country. Some routes require rabies titre test results, import permits, or government endorsement of the health certificate. Your destination country’s requirements apply regardless of which airline you use.

All airlines require IATA-compliant rigid crates for cargo pet transport. The crate must allow your pet to stand, sit upright, lie down, and turn around without touching the sides or top. It must have ventilation on at least three sides, a water container, and live animal labels. Soft-sided carriers are not accepted for cargo. For cabin travel, the carrier must fit under the seat in front of you.
