Confirm vaccination records (recommended)
7+ days before travelNo government-mandated vaccination certificates are required for domestic US pet travel. However, it is good practice to bring your pet's vaccination records. Some airlines may ask for proof of rabies vaccination.
Travel
Book airline pet spot
30+ days before travelContact your airline to reserve a cabin or cargo spot for your pet as early as possible. Airlines have limited pet spots per flight. Confirm fees, carrier size requirements, and any breed restrictions.
Get an appropriate carrier
14+ days before travelPurchase a carrier that meets your airline's size requirements (typically fits under the seat in front of you for cabin travel). Soft-sided carriers are accepted by most US airlines. Your pet must be able to stand, turn around, and lie down comfortably.
Arrive early at the airport
Arrive at least 2 hours before departure. Check in with an agent (not self-check-in) to register your pet and pay the pet fee. Your pet carrier counts as your personal item or carry-on (varies by airline).
Important Notes
No government-mandated health certificates, vaccinations, or customs documents are required for domestic pet air travel within the continental United States. Requirements are airline-specific only — contact your airline for carrier size limits, fees (typically $95–$150 each way), and any breed restrictions. Note: travel between the continental US and Hawaii has special requirements — see the US-HI route.
